WebApr 12, 2024 · A plastic damage model based on tension tests was established to further analyze damage evolution during reduction pretreatment. Experimental results showed that the distribution of the damage was characterized by microvoids near the surface and microcracks along the grain boundary at the center. WebNov 8, 2024 · A complete coarse grained (CG) model accomplishes the following: (1) it must represent the atomistic model as simplified CG “beads” that encapsulate a desired approximation of a group of atoms and (2) it must have a set of potentials called a force field that describe how the beads interact with one another. WebJan 12, 2015 · We generalize our view of a bonded-particle model (BPM) to consist of a base material (that is a packed assembly of rigid grains joined by deformable and breakable cement at grain–grain contacts) to which larger-scale joints can be added and whose mechanical behavior is simulated by the distinct-element method using the two- and … dr. pectol orthopedic greeneville tn
