APPLICATION OF ONE-DIMENSIONAL DIFFERENCE METHOD IN COMPOSITE PROCESS MECHANICS

Abstract

Abstract: As the deepening of the knowledge, a numerical method such as finite element, boundary element and etc. applying in composite process mechanics has been paid more and more attention. However, the tedious analysis process is discouraged and cannot be popularized to engineers. According to the characteristics of composite fabrication process, a one-dimensional difference algorithm is derived, which focuses on the variation of physical field distribution in the thickness direction of composite material. The simulation results show that the one-dimensional difference method has the characteristics of simple analysis, rapid calculation and enough precision. The variation of temperature field, curing field, material properties and other parameters in the composite are revealed, base on which the effects of curing cycle and thickness alteration of the laminate could be evaluated quickly.

Key words: difference algorithm, composite, process mechanics, numerical simulation
