晶界滑移传递是多晶材料变形过程中一个重要的微观力学过程。滑移传递过程可以根据相邻晶粒中活动滑移系的几何排列和作用于进入和可能的外出滑移系的临界分解剪应力的值来表征。我们提出了一个Matlab工具箱，使量化的晶界滑移传递性能和实验比较。使用图形用户界面，实验晶界数据可以直接导出作为输入文件的晶体塑性有限元模拟双晶体实验。
Slip transmission across grain boundaries is an essential micromechanical processes during deformation of polycrystalline materials. Slip transmission processes can be characterized based on the geometrical arrangement of active slip systems in adjacent grains and the value of the critical resolved shear stress acting on the incoming and possible outgoing slip systems. We present a Matlab toolbox which enables quantification of grain boundary slip transfer properties and comparison with experiments. Using a graphical user interface, experimental grain boundary data can be directly exported as input files for crystal plasticity finite element simulation of bicrystal experiments.
