FEA
1. Answer True or False below. (2 points each) When performing a nonlinear FE analysis, pressure is considered a “follower force.” Once an element aspect ratio exceeds 1, the larger the aspect ratio, the better the element performs. Eigenvalue buckling provides a good estimate of the Euler critical buckling load. It is important to include the Bauschinger effect in your FE model when simulating problems that experience large strain. Buckling can be considered as the inverse of stress stiffening....
