This is well known as the size effect. The extended finite element method (XFEM) is implemented to simulate the fracture process and size effect (scale effect) in the glass fiber reinforced polymer laminates weakened by holes or notches. The analysis shows that XFEM results are in good agreement with the experimental results specifying nominal strength and in good agreement with the analytical results based on the cohesive zone model specifying crack opening displacement and the fracture process zone length.}, type={Artykuły / Articles}, title={Extended finite element numerical analysis of scale effect in notched glass fiber reinforced epoxy composite}, URL={http://journals.pan.pl/Content/85004/PDF/05_paper.pdf}, doi={10.1515/meceng-2015-0013}, keywords={XFEM, extended finite element method, composite laminate, fracture processing zone, crack opening displacement}, }
