Performing a simulation for a pair of meshing spur gears. A torque of 15,000 lb-in is applied on the upper gear while both gears are at rest. The aim is to assess the maximum stress during the transmission of the torque. Normally, the maximum stress occurs at the contact or at the root of a tooth due to the bending of the tooth. Units are U.S. customary unit systems (in-lbm-lbf-s).

In this case study we analyze the maximum deformation and the distribution of von Mises stresses under the given distributed load and boundary conditions: The wrench is made of stainless steel and has a thickness of 3 mm. Pressure = 2Mpa Poisson's ratio = 0.27 Young modulus = 193GPa The entire hexagon on the right side of the wrench is fixed. All units are in millimeters

Consider a planar truss beam made of wooden timbers that can be used in parallel to make bridges. We determined the truss deflections at each joint under specified loading circumstances.

Let’s consider a case in which torque of 39 N-m is applied at the wheel center. The right half of the outer rim is constrained. Our aim is to assess the von-Mises stress on the rim to determine if engineers may have to alter the design configuration. Units: Metric unit systems (m, kg, N, s, V, A).

We compressed the Belleville spring by 1.0mm & then release the displacement completely. Normally, before running a simulation with plasticity, we'll assume a linear material to determine if the maximum stress exceeds the yield stress. If it is such, we will then explore the plasticity pattern of the Belleville spring. More importantly, residual stress will be examined after the spring is completely released. Also, we'll plot a force - displacement curve.

Imagine that your cellphone falls out your pocket and hits the concrete floor at a velocity of 5m/s. It was assumed that the phone body forms an angle of 20 degrees with the horizon when it hit the floor. The phone body is a shell of 0.5mm, made of aluminum. The concrete floor was modeled as an 160mm x 80mm x 10mm block.

Unit system used in the simulation is mm-kg-N-s

Picture an explosion, while such, an aluminum pipe blasts away due to explosive pressure and hits a solid steel column, deforms, then broken into pieces due to excessive strain. This is demonstrated using an explicit dynamic analysis system in Ansys Workbench 2021 R2. The solid steel column and the aluminum pipe is both 50mm in diameter and have a length of 200mm. The steel column is modeled as a rigid body fixed in space. The thickness of the aluminum pipe is 1mm thick. The pipe travelled at a speed of 300 m/s before smashing into the column.

Conducting a thermal analysis of an aluminum heat sink:

A fan forces air over all surfaces of the heat sink except for the base, where a heat flux q’ is prescribed. The surrounding air is 28°C with a heat transfer coefficient of h = 30 W/(m2 ⋅ °C)

(Part A~ Steady State thermal Analysis): Analyze the steady-state thermal response of the heat sink with an initial temperature of 28°C and a constant heat flux input of q’ = 1000 W/m2.

(Part B ~ Transient thermal Analysis): Suppose the heat flux is a square wave function with period of 90 seconds and magnitudes transitioning between 0 and 1000 W/m2. Analyze the transient thermal response of the heat sink in 180 seconds by using the steady-state solution as the initial condition.

(Part C ~ Thermal stress Analysis): Suppose the base of the heat sink is fixed. Analyze the thermal stress response of the heat sink by using the steady-state solution as the temperature load.
