本文例举了samcef的几个应用，利用局部非线性分析，分析了delamination,postbuckling and Collapse等三种情况下的响应。

In this paper,recent developments carried out in the SAMCEF finite element code and in theBOSS Quattro optimization toolbox are presented. Those developments aim atsimulating high non linear effects in laminated composite structures(post-buckling, collapse, delamination) and at optimising the composites withrespect to those structural responses. The use of Sequential Convex Programmingand of Surrogate-Based Optimization methods is discussed on industrial optimizationproblems.

    The use of advanced structural analyses and optimization methods hasbecome challenging in the design of composite structures. This paper presentedthree main kinds of recent applications. Depending on the problem, either agradient based or a surrogate-based optimization method can be used. Thiscomparison should be further investigated, especially when local non linearanalyses, such as delamination, postbuckling and collapse, are considered.Indeed, in such cases, few design variables are used, and both methods couldbecome competitive.
