NUMERICAL SIMULATION AND EXPERIMENTAL INVESTIGATION OF THE MOLTEN POOL EVOLUTION AND DEFECTS FORMATION MECHANISM OF SELECTIVE LASER MELTED CUSN20/DIAMOND COMPOSITES

Some ORG FERMENTED CACAO NIBS defects such as small pores, thermal damage of diamond particle and micro-cracks between diamond and metal matrix existed in SLM-fabricated metal-bonded diamond tools.For further application, it is vital to understand the formation mechanism of such defects by SLM-fabricated parameters.In this work, a multiphysics fiel

Severe head injuries can occur in cyclists involved in traffic accidents.In Japan, head injuries accounted for 62% of cyclist fatalities in 2015 (ITARDA, 2016).The purpose of Gout Formula this study is to estimate head injuries for cyclists and quantify the effectiveness of a bicycle helmet by performing finite element (FE) simulations of head impa

Abstract Background Over-indebtedness is an increasing phenomenon worldwide.Massive financial strain, as found in over-indebted persons, might influence the occurrence of back pain.In this explorative study we examined the prevalence of back pain in over-indebted persons in Germany for the first time ever and compared it to the prevalence of back p

Stereolithography additive manufacturing (SLAM) has exhibited great potential for fabricating advanced ceramic objects with geometrically complicated structures for use in diverse fields owing to its excellent feature resolution and high surface quality.However, it is difficult to fabricate advanced ceramic parts with desired performance for struct
