Version 4.2.1 - January 2012
Digimat-MF是一种平均场均化软件,用于预测多相复合材料的非线性本构行为.
Product DescriptionProduct Description
Digimat-MF是DIGIMAT的平均场均化模块,它能把局部材料特性定义为以下两项的材料特性的函数:

1. 基体相和夹杂物相
2. 复合微观结构形态(夹杂物的重量、外形和尺寸)

Digimat-MF是一款用户接口友好的微机械材料建模软件,用户可以按树形数据结构的指引,输入相位的材料特性、微观结构描述以及用于多相复合材料的加载.

  • DIGIMAT is a powerful tool that is giving us a new insight into our composite polymers. Its ability to model thermal expansion as a function of temperature, for instance, has been instrumental in understanding some subtle mechanism of warpage of injection molded parts. Vito Leo, Principal Scientist, Solvay Advanced Polymers
  • Digimat-MF homogenisation approach allows accurate prediction of the composite material stiffness, Lucien Douven, Design Engineer, DSM Engineering Plastics  
  • Integrated crash pads allow weight and cost reductions. Setting the absorption behavior is only possible through a rigorous composite modeling. An integrated structural analysis with DIGIMAT clearly reveals those benefits. Sandro Wartzack, Head of Simulation, Brose
