A study of shape memory effect in hydrogel/polyethylene glycol hybrid
Published 2014“…Brief experiments were carried out and results show that HG/PEG hybrids do not experience volume expansion when heated above melting temperature of hybrid. Hybrids containing high weight percentage of PEG (> ~200 wt% of PEG) showed thermo-responsive shape memory effect, while hybrids containing lower weight percentage of PEG (< 100 wt% of PEG) became hard and brittle. …”

Multi-scale Modeling Of Additive Manufacturing Process
Published 2016“…To this need, a multi-scale numerical study is carried out combining a three-dimensional finite element (FE) based macro-scale and a cellular automaton (CA) based meso-scale model in order to simulate the dendritic grain growth in the selective laser melting (SLM) technique. The macro-scale model successfully simulates the heat transfer and fluid flow physics associated with a moving melt pool. …”
