| Summary: | The usage of composite structures in aerospace industry is a common practice nowadays. One of the popular topic on aerospace composite research is the case of low velocity and compression after impact. This research will analyzing the effect of variations of laminate composite support condition and configurations on cohesive zone model configuration on damage assessment from the results of low velocity impact at carbon fiber reinforced plastics (CFRPs) composite. This research utilizing finite element (FE) method to simulate and analyze low velocity impact and compression after impact on laminate composite. The specimen chosen for this research is laminate composite Hexply AS4/8552, with two different support conditions. The damage profile in the form of delamination and working forces at low velocity impact simulation will be analyzed by the results of simulation. The compression force and displacement of compression plate will be analyzed to explain the buckling phenomenon at compression after impact test. The analysis shows that the support condition will affect the internal damage and residual strength of composite. The results of this research can be used as reference for research on low velocity impact and compression after impact on laminate composites.
