这是进行IGA分析的 Matlab代码.可用于进行1维，2维和三维的线弹性问题分析，并可以进行裂纹的扩展，夹杂等的计算。同时，包括Eular梁和Kirchhoff板在内的结构力学问题也可行。 (This is the the Isogeometric Analysis (IGA) Matlab code. The code supports one, two and three dimensional linear elasticity problems. Extended IGA for hole, inclusion and crack modelling is also implemented. Structural mechanics problems including Euler beam and Kirchhoff plates (rotation-free formulations) are implemented as well.)
