This lecture focuses on performing a static structural analysis of a beam subjected to a point load using Ansys Workbench. Building on previous lessons involving beams under a uniformly distributed load, this session highlights the differences in loading conditions and their effect on bending stress and deflection.

We consider a cantilever beam fixed at one end and free to displace in the Z direction at the other. A concentrated load of 100 kN is applied at the beam's center, with specific geometric dimensions and material properties defined upfront. The process involves creating and splitting the beam geometry in SpaceClaim, preparing it for precise load application at the center.

The workflow proceeds to Ansys Mechanical, where boundary conditions and mesh generation are applied.

In this comprehensive lecture, we explore the static structural analysis of a beam subjected to combined loads using Ansys Workbench 2020 R1. Building on previous lessons which focused on beams under continuous and point loads separately, this session integrates multiple load types, including a uniformly distributed load, a point load, and a moment, to create a more complex and realistic scenario often encountered in engineering practice.

The beam analyzed here is made from structural steel with a specified cross-section of 100mm by 100mm and a length of 10,000 mm. The loading conditions are clearly defined: a 12 kN uniformly distributed load is applied over the initial 3000 mm, a 10 kN moment is applied clockwise at the center, and a 4 kN point load acts downward beyond the 3000 mm mark. This multi-load configuration challenges the learner to apply their skills in setup, boundary condition application, and interpretation within the Ansys environment.

The lecture details an organized workflow starting with the verification of engineering data to ensure the material properties correspond to structural steel. Then the focus shifts to geometry creation in SpaceClaim, where key steps like selecting the XY plane, defining the beam dimensions, and splitting the geometry into segments for specific load application are demonstrated. This precision segmentation is crucial to accurately model the variation of loads and boundary conditions along the beam.

The meshing phase receives special attention due to the inclusion of a moment in this scenario, necessitating a finer mesh with an element size of 25 mm to capture detailed stress gradients and deformation responses. The instructor guides the user through generating this refined mesh and setting the appropriate boundary conditions—fixing one end of the beam and applying rollers support conditions at the other. These constraints model realistic support conditions pivotal in structural analysis.

Next, the forces and moments are meticulously applied to their exact locations. A uniform downward force over the specified segment, a point load on a distinct edge, and the moment at the beam's center are all accurately inputted, with corrective steps to orient vectors properly (e.g., applying a negative sign to moment components to achieve the clockwise direction). Such careful handling of load direction and positioning conveys best practices in simulation setup.

The lecture culminates in running the simulation and extracting key results. Maximum bending stress and deflections are compared with analytical calculations for validation—stress values closely matching at 183.5 MPa (versus 179 MPa analytically) and deflections being slightly higher at 92 mm compared to the analytic 85 mm. The instructor also demonstrates the utility of Ansys tools such as capturing simulation animations, exporting MP4 videos, and generating detailed reports including dates, times, and full documentation of loads and material data.

In this lecture, we delve into a practical approach to static structural analysis of beams using a line body model with an assigned beam profile. This technique offers a streamlined and efficient alternative to 3D geometry modeling by simplifying the beam into a 2D schematic line while still capturing critical structural behavior. The analysis begins with drawing the beam as a series of connected line segments on the XY plane, carefully segmented to accommodate different types of load applications and boundary conditions.

The workflow involves assigning a rectangular beam profile to the line schematic, which in this case measures 100 mm by 100 mm, representing a typical beam cross-section. Using structural steel as the default material choice consistent with engineering standards, the model is set up within Ansys Workbench's SpaceClaim geometry editor and prepared for simulation in the Mechanical module. Key decisions in this process include segmenting the line into smaller sections rather than a single long line to facilitate localized load applications and boundary supports, ensuring accurate response capture at various points along the beam.

Once geometry preparation is complete, the next stage involves applying multiple load types and boundary conditions. The beam is fixed at one end, allowing displacement at the other, imitating real-world structural constraints. The loads applied include point forces and a uniformly distributed load applied at strategic segments along the beam. Each load is carefully input with correct directionality and magnitude, measured in Newtons, to replicate realistic mechanical stress conditions.

After setup, detailed results emerge from the analysis, including the maximum bending stress, deflection, shear forces, and bending moment diagrams. One distinct advantage of using a line body with a beam profile is direct access to beam-specific results such as combined stress values that correlate closely to analytical calculations, providing valuable validation.

Building upon the previous lesson that explored static load scenarios, this session focuses on fatigue analysis—a crucial aspect when assessing the endurance and reliability of structures subjected to repetitive loading and unloading cycles. The geometry remains the same as before, allowing learners to differentiate the effects between static and cyclic loads clearly.

The analysis revolves around a steel geometry subjected to a fully reversed cyclic pressure load of 50 megapascals. The material choice, structural steel, is notable as it is the default in Ansys, simplifying initial setup and emphasizing the focus on fatigue rather than material definition. The mesh is kept consistent with the prior exercise at a one-millimeter element size to ensure comparability in the results.

This lesson methodically guides through creating the geometry in SpaceClaim, starting from drawing construction lines on the XY plane and applying precise dimensions, mirroring for symmetry, and rounding corners with specified radii. These detailed geometry-creation steps demonstrate practical CAD techniques crucial for accurate simulation input and reinforce best practices in preparing models for fatigue analysis.

Once the geometry is completed and imported back into Ansys Mechanical, the tutorial progresses with mesh generation and boundary condition applications, such as fixing the bottom surface and applying the prescribed pressure on the top surface to mimic the cyclic loading environment. These steps lay the groundwork for fatigue simulation by defining the physical constraints and loading accurately.

The core of the analysis is performed using the fatigue tool integrated within Ansys. The choice of a fully reversed loading condition replicates real-world scenarios where components experience alternating tensile and compressive stresses. The fatigue analysis then computes critical outputs including the minimum life expectancy of the structure, measured in cycles, and the factor of safety, a dimensionless value indicating structural reliability under cyclic stresses.
