laminat - Opis:
- A numerical study using the ANSYS 19.R3 environment is discussed in this research. This environment depends on the Virtual Crack Closure Technique (VCCT) method to test a double cantilever beam (DCB) according to the ASTM D5528 standard. Four kinds of laminate stacking sequences were considered. According to the results, the distribution of the strain energy release rates obtained along the delamination front in bending-extension and extension-twisting coupling had a good affinity with bending-extension coupling. At the same time, critical fracture toughness values were estimated to be around 87.9% of critical fracture toughness values bending-extension coupling. These results are proof of the bending-extension and extensiontwisting coupling success while testing the proximity to bending-extension coupling results of the DCB beam. These findings are compatible with the standard ASTM D5288. Therefore, the bending-extension and extension-twisting coupling provide a good indication of the delamination resistance during buckling tests of the composite.
