A predictive model for fracture in human ribs based on in-vitro acoustic emission data
(2021-09-01)
Article
Open AccessPurpose The aim of this paper is to propose a fracture model for human ribs based on acoustic emission (AE) data. The accumulation of microcracking until a macroscopic crack is produced can be monitored by AE. The ... -
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 ... -
