Analysis of Laminated Composite Plate under Low Velocity Impact using ABAQUS
In present work the performance of laminated composite plate under impact of low velocity is analyzed. In order to study behaviour of stress distribution in laminated composite plate due to low velocity impact finite element based model is constructed in ABAQUS. The symmetric plate consider is simply supported from all sides and impact of indentor is obtain at midpoint of the plate. Analysis is performed by varying parameters like shape of indentor, velocity of impact, different layup configuration and boundary conditions. Results obtained are well confined within limits of already existing experimental results. It is observed that conical shape indentor gives maximum amount of deflection and stresses for same velocity as compared to another indentor.
