May it be for environmental or economic reasons, mass reduction has become one of the main goals in mechanics. The short fiber thermoplastics composite is an interesting possibility since it presents a good compromise between a relatively easy process and mechanical properties. The aim of this work is to estimate and model the viscoelastic behavior at small strain of PC Lexan/Glass fiber composites. To meet this goal, a full field homogenization method based on solving the boundary problem through FFT is used. Virtual DMA experiments are used to build the master curve of the composite. They are later used to identify a macroscopic model for transverse isotropic short fiber composites. Finally, a meta-model is built to estimate the behavior of the composite at any given fiber volume ratio.

也许是出于环境或经济原因，减少质量已成为力学的主要目标之一。短纤维热塑性复合材料是一种令人感兴趣的可能性，因为它在相对容易的工艺和机械性能之间呈现出良好的折衷。这项工作的目的是估计和建模PC Lexan /玻璃纤维复合材料在小应变下的粘弹性行为。为了实现该目标，使用了基于通过FFT求解边界问题的全场均化方法。虚拟DMA实验用于构建复合材料的主曲线。它们随后用于识别横向各向同性短纤维复合材料的宏观模型。最后，建立一个元模型来估计在任何给定的纤维体积比下复合材料的性能。
