  • 对于ABAQUS中使用total time并以表格形式定义的幅值曲线，可以从.inp文件读取*Amplitude关键字和幅值数据，该幅值可应用于裂纹面牵引力（CFT）。ABAQUS总时间写入.dtp文件，在基于M积分计算SIF时访问时间和幅值。
  • 改进了节点力映射算法。在保留了网格面/节点的情况下，将执行一对一的节点力传递。如果重新划分了面网格，则将节点力映射到新网格。
  • NASTRAN Pload4和Force边界条件更新已解决几个问题。请注意，仅当Pload4施加到全局模型部分时，才支持具有指定方向的Pload4。
  • 对于ABAQUS的重力加载，修正了.inp文件中未指定单元集（或ID）的问题。
  • 区分ABAQUS和FRANC3D非线性轮廓积分，允许用户选择ABAQUS积分类型：K、J、C或T。
    • 改进了裂纹插入和网格划分库。表面网格划分和相关参数已修改，这些更改意味着V8.0.3将不能读取V8.1.fdb文件（除非删除或编辑MESH_PARAMS数据块）。改进后的库支持分叉裂纹。它还允许裂纹插入单个单元面以及对模板的其它改进。
    • 已移除旧的裂纹插入和网格划分库，在首选项和裂纹插入对话框中移除了“new library”选项。
    • 首选项对话框中的高级网格划分选项卡显示新的网格划分参数。franc3d.rc或franc3d.ini文件将使用新参数进行更新，忽略不再使用的旧参数。
    • 对于接近表面或在到达表面后分裂的前缘，有额外的检查和自动调整来拟合和增长裂纹前缘。在GrowCrack命令中添加了一个附加参数“check_fit”，以打开/关闭自动检查。默认情况下，如果使用GUI，检查是关闭的。
    • 支持计算单晶断裂参数，添加了在单晶最大剪切方向上解析SIF的功能。
    • 对动态雨流计数有几个编辑，包括选择da/dN而不是作为配对指标的选项。
    • 修复了SIF和T应力的表格显示，特别是对于没有载荷子步结果的情况。
    • 如果起始步不为零，则关闭SIF历史对话框中的初始裂纹长度选项。
    • 支持定义跨材料界面裂纹
    • 支持定义双材料界面裂纹
    • 支持定义对称表面裂纹
    • 支持定义有限体积的“厚”裂纹，即引入两侧裂纹面已经张开的裂纹，可用于韧性撕裂分析
    • 改进了模型表面的裂纹前缘模板交叉计算
    • 支持高/低周疲劳（LCF/HCF）联合加载
    • 增加了动态配对载荷类型
    • 添加了显示单位设置
    • 在用户首选项（Preferences）中增加打开或关闭微动疲劳和单晶断裂功能的选项
    • 添加了 Edit Crack Geometry… 菜单项来查看和编辑裂纹几何面片
    • 改进了对部分裂纹前前缘扩展的支持
    • 改进了有限元模型的输入/输出，以及边界条件的传输/映射
    • 更新了Python模块，支持版本3.7~3.9
