Numerical analysis of high speed concrete fragmentation using a meshfree Lagrangian method

A 3D computational homogenization model for porous material and parameters identification

“…Existing works on multiscale methods are limited mainly based on the FEM [46,52,53], or coupled FE-molecular dynamics [47,54,[56][57][58][59][60][61][62][63]75] techniques. It would be interesting in the future to explore the potential of other novel numerical methods to deal with the moving boundary problems such as meshless methods [39][40][41][42][43][44][45][48][49][50][51][64][65][66][67][68][69][70][71] and other types of discontinuum based methods [55,[72][73][74].…”

Analysis of concrete fracture using a novel cohesive crack method

“…Though methods exists that smear treat cracking in a smeared sense [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], it is believed that many applications require the description of discrete cracks. Crack propagation in concrete materials is associated with localization of the strain field, which, in case of fully open macrocracks becomes singular across the crack.…”

Fragmentation from spallation of RC slabs due to airblast loads

“…Both experimental and numerical studies have been conducted to investigate scabbing of RC members due to airblast loads [1][2][3][4][5][6][7][8]. For example, spallation damage of reinforced concrete slabs under blast loads was characterized by McVay [1] as: (1) no damage from initial state to a few barely visible cracks; (2) threshold for spallation damage from a few cracks and a hollow sound to a large bulge in the concrete with a few small pieces of spallation on the surface; and (3) moderate spallation damage from a very shallow spallation to spallation penetration up to one third of the plate thickness.…”
