1·The cause of flate cohesive zone is analyzed.
分析平坦型软融带的成因。
2·The cohesive zone is of "W" type in normal operation.
正常生产时，该高炉软熔带形状是“W”型。
3·Then, by means of the energy balance relation, a new cohesive stress law of Mode I crack is obtained which is only concerned with the surface energy density within the cohesive zone.
然后，利用能量平衡关系，得到仅与表面能密度相关的I型裂纹内聚力新的本构方程。
4·Nonlinear fracture behaviors of concrete materials are mainly caused by the cohesive stress along the fracture process zone.
混凝土裂缝端部断裂过程区的粘聚力分布是导致混凝土断裂呈现非线性特性的重要原因。
