Numerical Analysis Architecture of Mechanical Behaviors Simulation for FRP Laminated Strucutres
摘要
Abstract
The core of mechanical behaviors simulation for fiber reinforced plastic (FRP) laminated struc-tures is the construction of both material components′ mechanical responses and the coupling mecha-nisms between them .Simulation ultimate aim is to obtain the evolution process of time-related damage spatial field .Damage spatial field , material-property field and stress-strain distribution field interact with each other .The whole logical framework which describes the coupling relationship among three spatial fields can be defined as numerical analysis architecture .Within this architecture ,material compo-nents′mechanical responses ,nonlinear numerical analysis ,damage initiation criterion ,damage evolu-tion criterion ,size effect and in-situ effect are main modules .In this paper ,several methods that can constitute these modules are discussed ,and the promising ones are suggested to obtain a better simula-tion architecture . Finally , numerical examples under three different loading cases are conducted and compared with corresponding experimental data .The comparison results show the reasonability and ef-fectiveness of the numerical analysis architecture .关键词
