This thesis focuses on the measurement of the residual stress profile in fiber-reinforced composites by the incremental hole drilling method. The objective is to develop numerical and experimental tools adapted to the measurement of residual stresses and to study the thermal, chemical and mechanical behaviors of the composites during the drilling. A thorough and comprehensive understanding of the incremental hole drilling method is required to reliably determine the gradient of residual stresses in the composite. This method consist of drilling a small hole incrementally through the thickness of the material and measuring the induced relaxation strains for all increments. These relaxation strains are then converted into stresses using coeff...
