Abstract
A constitutive equation was developed for an infinite body in plane wave impact problem,
and implemented using the finite element software ABAQUS user subroutine. Bilinear material
behavior under monotonically increasing loading was considered for the constitutive equation. The
finite element governed by this type of material behavior can be used as an infinite body
transmitting longitudinal and shear plane waves, so that the number of finite elements can be
reduced in impact simulations. To test the developed method, results of a plate impact experiment
were examined. The numerical results show the accuracy of the developed constitutive equation.
