Simulation of Impact and Fragmentation with the Material Point Method
The simulation of high-rate deformation and failure of metals is has traditionally been performed using Lagrangian finite element methods or Eulerian hydrocodes. Lagrangian mesh-based methods are limited by issues involving mesh entanglement under large deformation and considerable complexity in handling contact. On the other hand, Eulerian hydrocodes are prone to material diffusion. In the Mat...
متن کاملSimulation of Material Plastic Flow and Morphology During Friction Stir Welding of Stainless Steel to Aluminum Alloy Dissimilar Joint
Today, steel to aluminum joints are used to facilitate transportation and fuel consumption. These joints are applied from nuclear, aerospace and naval to automobile and kitchen industries. According to previous studies fusion welding processes are not suitable methods for these joints, solid-state welding, especially friction stir welding, is a proper way to use for these joints. However, using...

متن کاملDENDRITE FRAGMENTATION IN THE SHEARED MELT BY FATIGUE EROSION MECHANISM OF SEMISOLID Al-Si ALLOY (A.356.0
Over the last few decades, there have been many mechanisms proposed to describe the formation of the non-dendritic microstructures during Semisolid Metal (SSM) processing; including dendrite fragmentation, spherical growth, cellular growth and recalescence. Dendrite fragmentation is the most popular mechanism of all these hypotheses. It is the purpose of the present article to examine the morph...
متن کاملUtilization of the Kinematic Runoff and Erosion Model in Predicting the Effects of Veg- Etation on Heavy Metal Contain- Ment in Southeast Kansas
In southeast Kansas, where mining activities ceased in the middle half of the twentieth century, heavy metals in residue materials have created surface contamination problems. The erosion losses of chat material, a by-product of mining activities, have elevated levels of cadmium, lead, and zinc in nearby farmland to phytotoxic levels for the crops normally planted. Selective vegetation is being...
