Dynamic response of normal moving load in an initially stressed transversely isotropic half-space (Q1067869)

In this paper the stresses developed in a transversely isotropic half- space under compressive prestressed conditions have been obtained due to a moving normal load on the rough surface. It has been shown that the existing prestresses have much effect on the development of incremental stresses due to normal load. The numerical calculations for developed stresses have been done for the case of ice for different values of prestressed parameters and have been presented in tabular form. The condition under which the fracture on the surface will take place has also been derived, and it has been shown that the critical velocity at which the fracture will take place is also a function of initial stresses present in the body. The numerical values for the velocities of moving load for generating fracture have been calculated for different prestressed parameters in case of ice.
