RESPONSE ANALYSIS OF LAMINATED COMPOSITES PRESSURE VESSEL SUBJECTED TO LOW VELOCITY IMPACT

Abstract

Composite materials most of the time used in the industry of marine and aerospace, the study care in understanding the response caused by the shock load in low velocity impact. The composite materials define as mixing two different materials to get good properties and light weight. The study involved impact load testing and a numerical analysis with Abaqus/Standard was used to compare with the experimental results, of many various variables of modeling, including(3)weight of impactor for open and closed end cylinders, three different thicknesses of layers of laminated composite cylinder. Various models are tested and results showed that the deflection and force with time are affected for these different models. Experimental and theoretical results showed good agreement for impact response magnitudes as well as contact forces with max. Percentage error of (7.5%).
