Abstract: Characteristic forms of differential equations for wave propagation in nonlinear media are derived directly from equations of motion and equations which combine the constitutive equations and the ...

Abstract: The Hertz problem for a rigid spherical indenter on a viscoelastic half-space was studied by Lee and Radok [1] in which the radius a(t) of the contact area is a monotonically increasing ...

Abstract: A study is given of elastic-plastic boundaries which start at the end x = 0 of a rod in one-dimensional wave propagation. The initial speed of the elastic-plastic boundaries at x = 0 and ...

Abstract: The elastic-plastic boundaries which start at the end of a tube in wave propagation of combined longitudinal and torsional stresses are studied. The longitudinal and torsional stresses applied ...

Abstract: An explicit solution is obtained of an integral equation which arises in several contact problems in linear viscoelastic bodies. The solution is valid for contact problems in which the ...

Abstract: Plastic wave speeds in materials whose elastic response is linear and isotropic while the plastic flow is incompressible and isotropically work-hardening are obtained. One of the three plastic ...

Abstract: The combined longitudinal and torsional waves in a linearly work-hardening thin-walled tube are studied. Explicit solutions are obtained for the stress paths in the stress space for the simple ...

Abstract: The contact problem of a symmetric rigid punch pressed at the midspan of a simply supported viscoelastic beam is studied. This is equivalent to a cantilever beam loaded at the free end against ...
