An understanding of the response of brittle and ductile materials under hyper velocity impact is required for analysis of the space debris and micro meteoroid impact flux via retrieved spacecraft surfaces. Brittle material surfaces exposed in Low Earth Orbit include solar arrays and windows. Laboratory experiments are able to access ...

In this video Simulation fluid structure interaction in ABAQUS has done. The ABAQUS has this capability to perform FSI analysis and create a appropriate coupling between CFD and Standard analysis. In this example the effect of air velocity over the short column has been investigated. The air domain was crated in ...
