Abstract

Generally manufacturing of composite materials is performed using trial and error method.The finite element method show the capability to optimize that process.The efficient formulation for simulating high speed impact usually uses explicit dynamic method. The purpose of this research is modelling impact loading on composite panel using finite element method as a part of preprototyping impact resistant composite material.The process of impact simulation on composite panel using explicit dynamic formulation can be done using commercial application software, that done with variation on impactor velocity (200, 400, 600, 800, 900, and 1000m/s), impactor geometry likes cone and blunt, Elasticity modully of lamina composite materials, the direction of fiber as symmetric cross plies and symmetric angle plies, and the thickness, 4, 6, 10 plies.The result showed that impact simulation on composite panel using this software can be performed well, the influence of impactor velocity shows increased the Von Misses Stress with average value 2.41% (in 200-400m/s), 1.59% (in 400-600m/s), 1.28% (in 600-800 m/s), 1.20% (in 800-1000m/s). Cone A type with the smallest area of contact have the best capability to penetrated compared with B type and blunt type. Symmetric angle plies have better impact resistant compared with symmetric cross plies.

Abstract

A truss is a structure that is a combination of several slender members. The high performance of the truss structure has been the first effort. The advancement of the truss structure analysis is required. Traditionally, analysis of truss structure is usually done with joints or section methods. There are not secure to solve with the theoretical statically determinate. Otherwise, more advanced techniques are compulsory. This report aims to use the finite element methods software to learn the behavior of truss structures and to compare with the theoretical of statically determinate manual calculation. The result has been shown that both methods had been given the similarity results. It means that the finite element software (Abaqus student editions software) entirely accurate to be used to analyze the 2D-trusses structure. Hopely its can be used to solve other complex problems in construction analysis.
