numerical modeling of machining processes is of significance in the parametric analysis and optimization of their performance. in this paper, a finite element-based model of abrasive waterjet (awj) cutting of a ductile material is presented with the help of an explicit, nonlinear finite element method. in this model, both solid-solid interaction and fluid-structure interaction are considered. t...

With the advent of high strength geogrids, the interest of civil engineers in using geosynthetics as reinforcement material in pavement construction has increased. An experimental study is carried out at IIT Delhi to understand the effect of geogrid in unpaved roads. Behavior of composite material, which comprises of Yamuna sand as subgrade and Water Bound Macadam (WBM) as base course is studie...

this work presents an experimental investigation of the influence of the six important machining parameters (tool nose radius, tool rake angle, feed rate, cutting speed, cutting environment (dry, wet and cooled) and depth of cut) on surface roughness & material removal rate in the machining unidirectional glass fiber reinforced plastics (ud-gfrp) composite using carbide (k10) cutting tool durin...

Manuscript received November 20, 2014. Of course, things can get complicated in nonlinear problems with large deformations (and rotations) because the final deformed area may be different from the initial area, among other things [1]. Stress is in fact a tensor [1]. It can be written in any of several forms as follows [1]. (Cauchy stress tensor shown in Fig. 2) In 3-D it can be written as, σ = ...
