Homework 4
Using quadratic tetrahedral elements, model the plastic latch shown. The latch is bonded to a flat
surface on the left and the right end is expected to repeatedly deflect 0.25 in. Generate the following
results: a plot of your model, a plot of
Homework 2
Part 1: 1-D Bars
Use ANSYS to calculate the displacement of the nodes, reaction forces at the walls, and the
internal force, stress, and strain in each element.
Part 2: Trusses
Use ANSYS to determine the displacement of each joint, the reaction
Homework 1
For the assembly of springs shown, use the finite element method to determine:
a. The displacement of all nodes
b. The reaction forces
c. The internal force in each spring
First, use the manual finite element method and solve the problem using
Homework 3
Conduct a plane stress analysis of the bicycle wrench shown. The thickness of the wrench is t. The
wrench is made of steel with a modulus of elasticity E = 200 GPa and a Poissons ratio = 0.32. Using
either ANSYS or Abaqus, create a free mesh wi

Investigate how the choice of material and thickness affect the strength and natural frequencies of the
cello as well as comparing the results both with and without symmetry. Shown in Figure 1 is the meshed
face with f holes
Project 1
Quadrilateral elements were used for all the meshes throughout the tests.
