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
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
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 ma
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.
