cohesive elements那一层在哪个increment发生的破坏

dava

做了这个例子，运行起来没什么问题。但是不知道cohesive elements那一层在哪个increment发生的破坏，哪位大侠给鉴定下？最好说明理由

dava

请教高手，顶

大侠们看看阿，谢谢了

提交分析前，在field output中输出STATUS。然后在后处理中，用display group / Element / Result value, 把field output 设为 STATUS.

见 http://www.simwe.com/forum/viewthread.php?tid=732468

ABAQUS Analysis User's Manual     
18.5.6 Defining the constitutive response of cohesive elements using a traction-separation description

Output：

In addition to the standard output identifiers available in ABAQUS (“ABAQUS/Standard output variable identifiers,” Section 4.2.1, and “ABAQUS/Explicit output variable identifiers,” Section 4.2.2), the following variables have special meaning for cohesive elements with traction-separation behavior:

STATUS： Status of element (the status of an element is 1.0 if the element is active, 0.0 if the element is not).

SDEG： Overall value of the scalar damage variable, .

DMICRT： All damage initiation criteria components.

MAXSCRT： This variable indicates whether the maximum nominal stress damage initiation criterion has been satisfied at a material point. It is evaluated as

MAXECRT： This variable indicates whether the maximum nominal strain damage initiation criterion has been satisfied at a material point. It is evaluated as

QUADSCRT： This variable indicates whether the quadratic nominal stress damage initiation criterion has been satisfied at a material point. It is evaluated as

QUADECRT： This variable indicates whether the quadratic nominal strain damage initiation criterion has been satisfied at a material point. It is evaluated as

ALLCD： The approximate amount of energy over the whole model or over an element set that is associated with viscous regularization in ABAQUS/Standard. Corresponding output variables (such as CENER, ELCD, and ECDDEN) represent the energy associated with viscous regularization at the integration point level and element level (the last quantity represents the energy per unit volume in the element), respectively.

For the variables above that indicate whether a certain damage initiation criterion has been satisfied or not, a value that is less than 1.0 indicates that the criterion has not been satisfied, while a value of 1.0 or higher indicates that the criterion has been satisfied. If damage evolution is specified for this criterion, the maximum value of this variable does not exceed 1.0. However, if damage evolution is not specified for the initiation criterion, this variable can have values higher than 1.0. The extent to which the variable is higher than 1.0 may be considered to be a measure of the extent to which this criterion has been violated.

兄 ，能否加我QQ 463077840，请教您问题。谢谢

我用过这个status，可是没什么效果，觉得很奇怪；其他的参量我试试看，any way，谢谢aba大侠
