摘要

本文研究了层状复合材料壳体非线性有限元模型的开发和验证，该模型考虑了一阶剪切变形理论（FSDT）和明确的厚度积分。该模型集成了中尺度损伤分析，考虑了基体和纤维的渐进失效。该模型与从三点弯曲试验片中提取的实验曲线包络线进行了比较，结果显示预测准确。

A nonlinear finite element analysis of laminated shells with a damage model

This paper presents a study on the development and validation of a nonlinear finite element model for laminated composite shells, that considers a first-order shear deformation theory (FSDT) and an explicit through-thickness integration. The model integrates a meso-scale damage analysis that considers progressive matrix and fiber failures. The model is compared with envelopes of experimental curves extracted from 3-point bending test coupons and shows accurate predictions.
