Virtual crack closure analysis predicts failure in composites.(TESTING/ANALYSIS)
Advanced Materials & Processes, October, 2005
A comprehensive implementation of the Virtual Crack Closure Technique (VCCT), a technology that Boeing developed for predicting fracture and failure in laminated composite materials, has been refined by Abaqus Inc., Providence, R.I. It is said to accurately simulate delamination in composite structures.
VCCT for Abaqus refines the Boeing technology and integrates it as part of the familiar Abaqus analysis environment. The software is compatible with Version 6.5 and is available immediately. The software allows engineers to identify the overall load at which a crack initiates and to predict the behavior of the structure as the crack propagates. It also helps users understand the stability and load-carrying capacity of the composite structure after failure, a...
