Numerical analysis of the DCB test configuration applicability to mechanically coupled Fiber Reinforced Laminated Composite beams

This article presents a numerical FE study on the mode I strain energy release rate (SERR, GI) distribution along delamination front in mechanically coupled laminated composites deformed in accordance with the DCB test configuration as described in the ASTM D 5528 Standard. The standardized boundary conditions were compared to the freed ones and two kinds of the laminate stacking sequence were considered. The bending–twisting coupling having the...
