First, phenomena at the origin of residual stresses in injection molding of thermoplastic polymers are described, and the specificity of fiber reinforced thermoplastic is introduced. Heterogeneous cooling associated with mechanical behavior variations leads to thermal stresses. Frozen-in pressure induced stresses are specific to the injection molding process. Fibers induce heterogeneity and anisotropy of mechanical behavior and thermal shrinkage. Second, a measurement technique based on the layer removal method and measurement of the bending moment is presented. It allows the determination of residual stresses in anisotropic materials such as fiber reinforced thermoplastics. The influence of the milling process is discussed. Tensile stresse...
