Question

b) List the four material properties needed to perform analysis using a bilinear material c) Describe the boundary conditions needed to impose a symmetry plane when using shell elements. d) Provide an example of when you would use the explicit dynamics analysis system. Describe adaptive meshing.

Answer 1

please provide thumbsup and support my efforts..!

the analysis deformation, c) adaptive mething in non-linear Simulations the material in the structure on process undergues many very huge deformations. These deformations distrot the finite element mech, often to the point where the mesh is unable to provide accurate results sor) terminates for numerical reasons In such simulations, it is essential to use adaptive Meshing tools to intermittently minimize the distortion in the mesh, adaptive mesh donains define the regions of the model where the mash can move independently of material charockerboties the adaptive meshing capability regulir ar intervals to recence element distorsion and to maintain good element aspect rattos. The Sam mesh topology is maintained ie, the number of elements and nodes and their connectivity do not change - thanking you - * please provide upote and support my efforts* Have day The primang cho of are in & The mesh is Smoothed at a nice
