Elastic-slip interface effect on dynamic stress around twin tunnels in soil medium subjected to blast waves
TL;DR: In this article, an elastic-slip interface model is introduced to analyze the dynamic response of twin tunnels subjected to blast waves, where the blast waves are expressed by Fourier-Bessel expansion method of wave function, and the wave field is superimposed by Graf coordinate transformation method.

Effect of unconfined compressive strength of rock on dynamic response of shallow unlined tunnel
TL;DR: In this article, the effect of different unconfined compressive strengths (UCS) of rock on the extent of damage produced due to blast loading has been investigated, and a relation has been proposed to understand the damage caused by TNT blast loading in a shallow unlined tunnel.

Improving the compressive performance of foam concrete with ceramsite: Experimental and meso-scale numerical investigation
TL;DR: In this paper, the responses of ceramsite foam concrete were investigated experimentally and numerically with meso-scale model, and the failure mode, compressive strength, plateau stress, and energy absorption capacity of the LWAFC with an averaged loading rate of 1m/s were systematically investigated.

A plastic-damage model for concrete
TL;DR: In this article, a constitutive model based on an internal variable-formulation of plasticity theory for the non-linear analysis of concrete is presented, which uses a new yield criterion which matches experimental data quite well and it accounts for both elastic and plastic stiffness degradations effects.
