Modelling of dynamic behaviour of concrete materials under blast loading
TL;DR: In this article, a constitutive model for predicting the dynamic strength and damage of concrete subjected to blast loading is developed, which stems from the continuum fracture mechanics of microcracks nucleation, growth and coalescence to formulate the evolution of damage.

Prediction of debris launch velocity of vented concrete structures under internal blast
Yonglong Lu,K. Xu +1 more
TL;DR: In this paper, the authors present a simple predictive method for the debris launch velocity from a concrete storage magazine subjected to internal blast load, with particular focus on the effect of initial vent openings.

Crack propagation analysis with Galerkin boundary element method
TL;DR: In this paper, the authors described the application of symmetric Galerkin boundary element methods (SGBEM) for the analysis of a 2D crack propagation problem and derived the sub-domain SGBEM for crack problem.

Elastoplastic analysis using quasi‐higher order symmetric Galerkin boundary element method
TL;DR: In this paper, an interpolation method called the quasi-higher order element method (QHOEM) is proposed for solving elastoplastic problems using symmetric Galerkin boundary element method.

Multiple-crack analysis with the quasi-higher-order symmetric Galerkin boundary element method
TL;DR: In this article, the symmetric Galerkin boundary element method (SGBEM) was used for the analysis of a two-dimensional linear elastic crack problem, which can deal with any number of traction-free cracks within a single domain.
