Answer #1

d) The difference between geometric nonlinearity and material nonlinearity is deformation.

geometric nonlinearity: The deformation of the mechnanical part depends on the dimensions of the part it may be a large or small deformation based on the geometric nonlinearity we will define the deoformation.

example: small deoformation:cubes,shells ; large deformation:metal forming,tire analysis

material nonlinearity:it involves in the current deformation,deformation history,rate of deformation,temperature and pressure of the material.

example:rubber and plastic material

geometric nonlinearity material nonlinearity
large displacement current displacement
small deformation deformation history

e) ans: in finite element analysis self weight of the structure will be added based on the density of the material

    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....
