ANSYS Mechanical analysis of a wrench-like body modeled in SOLIDWORKS. Images include isometric views of force vector with fixed support on bottom face, three mesh sizes cases, total deformation and von-Mises stresses for each of the three meshing cases. I learned how meshing sizes impact varying metrics in an FEA. Here, total deformation converged at 0.061 mm across all three mesh densities, but peak von-Mises stress kept rising with refinement (48 to 52 to 58 MPa) with no sign of leveling off, indicating a stress singularity at the sharp fillet where the shank meets the base rather than a converged physical value. This would neccesitate changes in CAD for the FEA to provide trustworthy values for factor of safety caculations to allow for advancing to manufacturing.

ANSYS Mechanical analysis of an anti-vibration grommet, the type commonly used in aircraft and spacecraft to isolate delicate equipment from vibration. The SolidWorks model was pulled directly from McMaster-Carr, part number 9311K186. Figures include the mesh and stress relaxation curve. The animations display total deformation (true scale), equivalent (von Mises) stress, and strain energy. Instead of using the soft rubber material the part ships with, I created a custom material to learn the Engineering Data stage of the FEA workflow, based on hard rubber (ebonite), with a Young's modulus of 3 GPa, a Poisson's ratio of 0.35, and a non-linear elastic profile. The inner flange faces were set as fixed supports, with a simulated clamping force of 2000 lb applied through two washers on the top and bottom surfaces. 

ANSYS Mechanical analysis of a clamshell-style pressurized spherical tank (STEP file here). The tank has internal and external nominal diameters of 62.99 in and 64.57 in, giving a nominal wall thickness of 0.79 in. Figures show the mesh from both internal and external views. Two custom materials were modeled to compare performance under load: aerospace-grade ASM aluminum 2219 and Latrobe D6AC steel, tempered at 600°F for its higher-strength condition (250 ksi yield, 280 ksi ultimate). The tank was loaded at an internal pressure of 3000 psi with a fixed support on the bottom face of the supporting truss. Animations show total deformation for each material at 10x scale. The D6AC steel deformed a maximum of 0.0472 in at the center of the bottom half of the tank; the 2219 aluminum deformed 0.1363 in at the center of the top half, nearly three times as much. That ratio tracks closely with the difference in elastic modulus between the two materials at STP, 30.5 Mpsi for D6AC versus 10.6 Mpsi for 2219, which is the dominant factor driving deformation in an otherwise identical, linear-elastic structure.
