dc.description.abstract | Design of sustainable civil infrastructure requires that the built environment is resilient against natural and man-made hazards which can cause catastrophic failures. As a result, high rates of strain (102- 104/sec) are generated in the soil which plays a significant effect on the strength and stiffness of soil. In this paper, we investigate the high strain-rate behavior of sand by developing a rate-dependent, multi-axial, viscoplastic two-surface constitutive model based on the concepts of critical-state soil mechanics. Perzyna’s overstress theory and non-associated flow rule are used in this model. The rate-dependent model parameters are determined from experimental data of split Hopkinson pressure bar test under high rate loading. Model performance is demonstrated for various sands. | en_US |
