The dynamic response and critical state of an inelastic simply supported column under an axial impact are studied. This problem is analyzed by solving the dynamic Bernoulli‐Euler equation with an axial inertia effect within the framework of finite difference approach. The influence of strain‐rate effects on the dynamic response is first examined by using an elastic‐viscoplastic theory, and then the critical values of an initial velocity and a mass of striking body for losing stability are… CONTINUE READING
