摘要
A parametric modeling approach is proposed based on secondary development of Abaqus and a plug-in tool is designed for emulation analysis on cellular structures through graphical user interface. Firstly, star honeycomb (SH), double-headed arrow honeycomb (DAH), and re-entrant hexagon honeycomb (RHH) are chosen, and prediction models are established to estimate their mechanical properties based on homogenization theory. Then, equivalent Poisson's ratio, elastic modulus and platform stress are verified through quasi-static compression tests and simulation analysis on DAH. Subsequently, the corresponding prediction models can be integrated into the plug-in tool to pre-analyze mechanical properties of cellular structures by inputting various geometric parameters. Secondly, parametric modeling on the three cellular structures is executed. Then, attribute assignments of material, load and constraint properties are set based on Python program. Based on this, the plug-in tool is utilized to output geometric models automatically and acquire target output data employed to draw curves by MATLAB. Then, quasi-static compression tests on RHH are performed to verify the accuracy of parametric models generated by plug-in tool. Eventually, multi-condition impact mechanical properties of RHH and the influences of structural parameters on mechanical properties of the SH are investigated based on the developed plug-in tool.
