A stochastic model for soft tissue failure using acoustic emission data
(2015-07-15)
Article
Open AccessThe strength of soft tissues is due mainly to collagen fibers. In most collagenous tissues, the arrangement of the fibers is random, but has preferred directions. The random arrangement makes it difficult to make deterministic ... -
