"探索与优化：二维骨料生成程序及代码详解",《基于MATLAB的圆形与卵石骨料生成程序及算法详解》,二维骨料生成程序和代码--------------------------------------------------圆形骨料：高颗粒填充比，尺寸多级配，任意尺寸分布，几何周期。卵石骨料，高颗粒填充比，可以尺寸多级配，任意尺寸分布。--------------------------------------------------圆形骨料的填充算法无详解，只可使用，填充速度很快；卵石骨料基于椭圆形，加入变形因素形成，骨料的填充算法有详解，并以matlab代码编写，可供学习和进一步的修改以满足不同需求。--------------------------------------------------由于高颗粒填充模型通过python语言在abaqus中建模较慢且容易卡崩，故不提供可直接在商用有限元软件建模的脚本，由其他方式进行骨料的构建和填充得到几何参数，然后可自行结合宏录制和python语法直接在abaqus中构建几何。,二维骨料生成程序;
