Hi all,
I am analyzing a scenario where a part impacts another part and wanted to find the stresses induced in the material (see attached picture). From what I have gathered I should use conservation of energy where the kinetic energy of the moving piston is transferred to cause deformation of the material (strain energy where dU = Pdx). The housing is fixed. The piston is made of weaker plastic and therefore I assume this will fail first. I am a little confused on how to apply the strain energy to this scenario as most the examples I have seen apply to a constant CSA part that hits a fixed boundary. Any help is appreciated. Thanks
