A foam rod of length L = 50 mm and diameter d = 10 mm has a Poisson’s ratio ν = −0.7 and a Young’s modulus E = 10 MPa. The rod is to be inserted into a hole with diameter δ = 9 mm. To do this the rod is first axially compressed and then slid into the hole after which the axial com- pression is released. How much axial compression stress is required for the insertion step? After the axial compression is released, what is the stress state in the rod? Assume the plate is rigid and that there is no friction between the rod and the plate.
