Fatigue behaviour of thick-walled GFRP-Laminates under tension, compression, bending and multiaxial loads

本文研究了厚壁玻璃钢层合板在静荷载和循环荷载作用下的强度。这是一个主要的假设，即众所周知的在压缩厚壁下的静强度下降（部分也在拉伸下发现）也将在循环加载下发现。这一假设通过包括拉力、压缩、弯曲和多轴加载在内的综合试验程序进行了验证。它是由高保真模拟补充。这些模型反映了样品内部结构的实际形态。该程序只能在与合作伙伴密切互动的情况下完成：ILK（样品制造），IPC（补充测试程序）和IKT（无损检测）。测试的IFL部分仅限于室温。

This proposal investigates the strength of thick-walled GFRP-laminates under static and cyclic loading. It is the main hypothesis that the well-known drop in static strength under compression thick-walled (which is partly also found under tension) will also be found under cyclic loading. This hypothesis is checked by means of a comprehensive test program, comprising tension, compression, bending and multi-axial loading. It is complemented by high-fidelity simulations. These models reflect the actual morphology of the internal structure of the specimens. The program may only be accomplished in close interaction with the partners: ILK (for specimen manufacturing), IPC (for a complementary test program) and IKT (non-destructive inspection). The IFL part of the tests is limited to room temperature.
