Failure risk in powder-compacted parts - David Gethin (Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering, 2010)
This article represents a first attempt at using a material model that captures statistical property variation to predict the failure probability by cracking in a powder compacted part. Failure in the powder compaction process is extremely difficult to model as the material response is density dependent and where cracking occurs this is usually associated with a dilation mechanism. This paper shows how a statistical model may be used to predict such failure, including accounting for material variation.
