Development and Testing of Mechanical Properties Simulation System for Composite Laminates

Based on Visual Fox Pro 9.0 platform, a simulation data system for mechanical properties of composite laminates is established in this paper. The system mainly includes the following modules: maintenance module of database for mechanical properties simulation of composite laminates, query module for mechanical information of composite laminates and automatic generation module of APDL code for strength simulation of composite laminates. Then, the data connection relationship among the modules is established, which constitutes the overall framework of the database. Finally, the interface of the module is designed in detail, by adding various controls and new methods, programs and attributes, and compiling corresponding VFP codes. The test and analysis prove that the system can predict the mechanical properties of composite laminates accurately to a certain extent, and it can guide the laminate structure.
