Efficient progressive failure analysis of multi-stringer stiffened composite panels through a two-way loose coupling global-local approach

A two-way coupling global-local finite element approach which has demonstrated its potential on the basis of representative test cases in earlier work, is used for the progressive failure analysis of large stiffened composite panels. In order to realize the capability of the approach to analyze larger panels, the efficiency of the analysis is enhanced and improved rules for the choice of the size of local models are developed. null The potential...
