TWO DIMENSIONAL STRESS WAVES RESULTING FROM AXISYMMETRIC IMPACT OF FINITE-LENGTH RODS

A numerical analysis has been developed to study the dynamic problem of axisymmetrically impacting, finite-length rods. The analysis is based upon the method of characteristics and the medium is assumed elastic/viscoplastic, satisfying von Mises yielding criterion, isotropic hardening, and viscoplastic incompressibility. The numerical results are in general comparable to those of elastic-plastic solids by the numerical finite-difference method. The paper examines the influence of viscoplasticity on two-dimensional stress wave propagation, dynamic Saint Venant's principle, reflection of two-dimensional stress waves from free boundaries, and internal phenomena due to stress wave interactions.
