1、XFEM*DAMAGE STABILIZATIONSpecify viscosity coefficients for the damage model for fiber-reinforced materials, surface-based cohesive behavior or cohesive behavior in enriched elements.*损伤稳定 指定纤维增强材料、基于表面的粘结特性或增强单元的粘结特性的损伤模型粘度系数。This option is used to specify viscosity coefficients used in the viscous
2、 regularization scheme for the damage model for fiber-reinforced materials, surface-based traction-separation behavior in contact or cohesive behavior in enriched elements. For fiber-reinforced materials, you can use this option in conjunction with the *DAMAGE INITIATION, CRITERION=HASHIN and *DAMAG
3、E EVOLUTION options; for surface-based traction-separation behavior, you can use this option in conjunction with the *DAMAGE INITIATION, CRITERION=MAXS, MAXE, QUADS, or QUADE and *DAMAGE EVOLUTION options.这个选项是用来指定损伤模型的粘度系数用于粘性正规化，损伤模型包括纤维增强材料，基于表面的粘结特性或增强单元的粘结特性。对于纤维增强材料，你可以使用此选项与*DAMAGE INITIATION
4、 损伤萌生，判据= HASHIN 和 *DAMAGE EVOLUTION 损伤演化选择相联系;对于表面的拉伸缺口特性（本构曲线） ，你可以使用此选项与 *DAMAGE INITIATION 损伤萌生，判据= MAXS ， MAXE ，QUADS, or QUADE 和 *DAMAGE EVOLUTION 损伤演化选择相联系。Products: Abaqus/Standard Abaqus/Explicit产品： Abaqus /标准 Abaqus /显式Type: Model data 类型：模型数据Level: Model级别：模型 参考文献：References:没有与此相关的参数选项。
5、数据来确定粘度系数的纤维增强材料 第一行： 粘滞系数在纵向拉伸方向。 粘滞系数的纵向压缩的方向发展。 粘滞系数的横向拉伸方向。 粘滞系数横向压缩的方向发展。 数据来界定粘度系数出现的牵引分离行为或凝聚力行为的丰富内容： 第一个（只）行： 粘滞系数。*CONTROLSReset solution controls.重置求解控制Warning: This option is not needed in most nonlinear analyses, except for use with the parameter ANALYSIS=DISCONTINUOUS. However, if extr
6、eme nonlinearities occur, this option may be needed to obtain a solution. “Commonly used control parameters,” Section 7.2.2 of the Abaqus Analysis Users Manual, contains a discussion of the types of problems that may occur and the use of the *CONTROLS option to overcome these problems. This option c
7、an also be used in some cases to obtain a solution in a more efficient manner. Use of the option for this latter purpose is intended for experienced users only.警告：此选项在大多数非线性分析是不需要，除用于参数ANALYSIS=DISCONTINUOUS。然而，如果发生极端非线性，此选项可能需要获得一个解决办法。 “Commonly used control parameters,” Section 7.2.2 of the Abaqu
8、s Analysis Users Manual，讨论了各类可能出现的问题和使用*CONTROLS 选项来克服这些问题。此选项在某些情况下还可以以更有效的方式获得解。有经验的用户可以使用后者选项。Product: Abaqus/Standard Type: History data Level: Step General solutions controls-Required, mutually exclusive parameters: ANALYSIS Set ANALYSIS=DISCONTINUOUS to set parameters that will usually improve
9、 efficiency for severely discontinuous behavior, such as frictional sliding or concrete cracking, by allowing relatively many iterations prior to beginning any checks on the convergence rate. This parameter overrides any values that may be set for the variables and on the data lines associated with
10、PARAMETERS=TIME INCREMENTATION. A less efficient solution may result if this parameter is set in problems that do not exhibit severely discontinuous behavior.分析设置 ANALYSIS=DISCONTINUOUS 对于严重不连续行为通常会提高效率，如摩擦滑动或混凝土开裂，通过相对较多的初始迭代对收敛速度任何检查。设置 PARAMETERS=TIME INCREMENTATION 将重写数据行中设置的 and on 变量值。这个参数设定可能
11、使得一个不太有效的解决办法可能不会表现出严重的不连续的行为。PARAMETERSSet PARAMETERS=FIELD to set parameters for satisfying a field equation. In this case the FIELD parameter can be used to define the field for which the parameters are being given. If the FIELD parameter is omitted, the parameters are being set for all fields th

13、果该 FIELD 参数省略， RESET Include this parameter to reset all values to their defaults. The option should have no data lines when this parameter is used.TYPE Set TYPE=DIRECT CYCLIC to set parameters that will be used to control the stabilized state and plastic ratcheting detections and to specify when to impose the periodicity condition for direct cyclic analysis.Set TYPE=VCCT LINEAR SCALING to set the parameter that will be used with linear scaling for a VCCT debonding analysis.
