Scientists at Kyushu Institute of Technology Target Safety Engineering

摘要

2011 OCT 26 - (VerticalNews.com) -- According to the authors of a study fromrnKitakyushu, Japan, "Several types of singular stress fields may appear at the corner where anrninterface between two bonded materials intersects a traction-free edge depending on the materialrncombinations. Since the failure of the multi-layer systems often originates at the free-edgerncorner, the analysis of the edge interface crack is the most fundamental to simulate crackrnextension."
