Reconstruction of a 2D stress field around the tip of a sharp material inclusion

Procedia Structural Integrity, 2016
AbstractThe stress distribution in the vicinity of a sharp material inclusion (SMI) tip exhibits a singular stress behavior. The strength of the stress singularity depends on material properties and geometry. The SMI is a special case of a general singular stress concentrator (GSSC).

FLAW'S RECONSTRUCTION IN MULTI-LAYERS COMPOSITES

Advanced Engineering Research, 2009
There are offered methods of faults reconstruction in stratified composites - stratifications (the interface flaws). Inverse geometrical problems of reconstruction of flaws are reduced to a solution of sequence of systems of the BIE obtained on the basis
