The composite is a combination of two or more materials that are combined at a macroscopic level and are not soluble in each other. Fibre-reinforced composites are popularly known for their supreme properties such as high strength to weight ratio, high impact strength, high fatigue resistance, etc. Hence they are most commonly used in Aerospace, Automotive, Marine structures, and Defence sectors. Composites have high strength in the direction of the fibre, lesser in strength in the transverse direction. Transverse loads cause Barely Visible Impact Damage (BVID) which results in catastrophic failure of composites and structure. BVID has been the topic of continual research due to its complexity in early detection and prevention. In present study Low-velocity impact response and damage analysis of CFRP and stiffened CFRP laminates using finite element modeling with LS-DYNA has been performed for assessing delamination at the interface and influence of other parameters such as material models, the influence of stiffener and influence of impactor shape on the impact response the composite material is also studied.
