Shock Wave Response of Porous Materials: From Plasticity to Elasticity
Aiguo Xu, Guangcai Zhang, Yangjun Ying +2
Shock wave reaction results in various characteristic regimes in porous material. The geometrical and topological properties of these regimes are highly concerned in practical appl…
Simulation study of shock reaction on porous material
Aiguo Xu, Guangcai Zhang, X. F. Pan +1
Direct modeling of porous materials under shock is a complex issue. We investigate such a system via the newly developed material-point method. The effects of shock strength and po…
Morphological characterization of shocked porous material
Aiguo Xu, Guangcai Zhang, X. F. Pan +2
Morphological measures are introduced to probe the complex procedure of shock wave reaction on porous material. They characterize the geometry and topology of the pixelized map of…
Generalized Interpolation Material Point Approach to High Melting Explosive with Cavities Under Shock
X. F. Pan, Aiguo Xu, Guangcai Zhang +1
Criterion for contacting is critically important for the Generalized Interpolation Material Point(GIMP) method. We present an improved criterion by adding a switching function. Wit…
Three-dimensional multi-mesh material point method for solving collision problems
Xiaofei Pan, Aiguo Xu, Guangcai Zhang +3
Contact algorithm between different bodies plays an important role in solving collision problems. Usually it is not easy to be treated very well. Several ones for material point me…
Material-Point Simulation to Cavity Collapse Under Shock
Aiguo Xu, X. F. Pan, Guangcai Zhang +1
The collapse of cavities under shock is a key problem in various fields ranging from erosion of material, ignition of explosive, to sonoluminescence, etc. We study such processes u…
