ABSTRACT

This projectaims at reduction of weight of  Liquid petroleum gas(LPG). So, the finite element analysis of Liquefied Petroleum Gas (LPG) cylinders made of Steel and Fiber Reinforced Plastic (FRP) composites has been carried out. Finite element analysis of composite cylinder subjected to internal pressure is performed. Layered shell element of a versatile FE analysis package ANSYS (version 9.0) has been used to model the shell with FRP composites.

A number of cases are considered to study the stresses and deformations due to pressure loading inside the cylinder. First, the results of stresses and deformation for steel cylinders are compared with the analytical solution available in literature in order to validate the model and the software. The weight savings are also presented for steel, Glass Fiber Reinforced Plastic (GFRP) composites and Carbon Fiber Reinforced Plastic (CFRP) composite LPG cylinders. Variations of stresses and deformations throughout the cylinder made of steel, GFRP and CFRP are studied.

A complex orthotropic mechanics of FRP composites has been studied and discussed in brief to have some understanding of behavior of FRP composites. In addition to that an introductory Finite Element Method has also been presented on the basis of which the cylinder has been analyzed.
