| Abstract: | Application of EPS(expanded polystyrene) in embankment has been focused on in China in recent years.Unconfined uniaxial compression tests and fatigue tests on EPS of various densities were conducted with MTS to investigate the stress-strain relationship and fatigue performance.It was shown that the constitutive relation of EPS took on characters of a multi-section function and there was a threshold stress in the process of the materials' fatigue failure.The constitutive equation and fatigue formulation,as well as the compression strength and elastic modulus used in design,were presented in this paper. |
