Abstract
The bimodular property of geomaterials (different Young’s moduli in tension and compression) leads to complex modes of wave propagation. For the harmonic pulse loading when compressive pulse precedes a tensile pulse, an exact analytical solution is obtained and compared to a numerical one. For the loading case when a tensile pulse precedes a compressive pulse, numerical results are given. In the latter case, a phenomenon of strain disappearance caused by the collapse of the pulses is observed. In both cases shock waves are not formed and hence the stress concentrations capable of compromising structural integrity are not produced.
