BEAM188单元中文说明 下载本文

Output section forces/moments and strains/curvatures extrapolated to element nodes

输出截面力、弯距和应力、曲率,外推到单元节点。

Note

KEYOPT(6) through KEYOPT(9) are active only when

OUTPR,ESOL is active. When KEYOPT(6), (7), (8), and (9) are active, the strains reported in the element output are total strains. \associated with the element has plasticity, plastic strain and plastic work are also provided. Alternatively, use PRSSOL in /POST1.

仅仅当outpr ,esol是激活状态的时候,Keyopt(6)通过keyopt(9) 来激活。当keyopt(6) 、(7)、(8)和(9) 都激活的时候,在单元输出中的应变是总应变。这个“总”包括温度应变。当单元材料是有塑性的时候,能够提供塑性应变和塑性作业。在/post1,运用prssol命令查看结果。

Output control at section integration point (not available when section subtype = ASEC):

输出控制在截面积分点(当截面的亚类为ASEC 的时候不可用)

0 -- Default; none

默认;无

1 --

Maximum and minimum stresses/strains

最大和最小应力、应变

2 --

Same as KEYOPT(7) = 1 plus stresses and strains at each section point

和keyopt(7)=1 相同,加上每个截面点上的应力和应变。

KEYOPT(8)

Output control at section nodes (not available when section subtype = ASEC):

输出控制在截面节点(当截面亚类为ASEC 的时候不可用)

0 --

Default; none

默认;无

1 --

Maximum and minimum stresses/strains

2 --

Same as KEYOPT(8) = 1 plus stresses and strains along the exterior boundary of the cross-section

和keyopt(8)=1 相同,加上沿着截面外表面的应力和应变。

3 --

Same as KEYOPT(8) = 1 plus stresses and strains at each section node

和keyopt(8)=1 相同,加上每个截面节点的应力和应变。

KEYOPT(9)

Output control for extrapolated values at element nodes and section nodes (not available when section subtype = ASEC):

在单元节点和截面节点外推数值用的输出控制(当节点亚类为ASEC 的时候不可用)

0 -- Default; none

默认;无

1 --

Maximum and minimum stresses/strains

最大和最小应力、应变

2 --

Same as KEYOPT(9) = 1 plus stresses and strains along the exterior boundary of the cross-section

和keyopt(9)=1 相同,加上沿着截面外边缘的应力应变。

3 --

Same as KEYOPT(9) = 1 plus stresses and strains at all section nodes

和keyopt(9)=1 相同,加上所有截面节点的应力和应变。

KEYOPT(10)

User-defined initial stresses:

用户定义初始应力

0 --

No user subroutine to provide initial stresses (default)

无用户子程序来提供初始应力(默认)

1 --

Read initial stress data from user subroutine USTRESS

从用于子程序ustress 来读取初始应力。

Note

See the Guide to ANSYS User Programmable Features for user written subroutines.

参考Guide to ANSYS User Programmable Features帮助用户书写子程序。

KEYOPT(11)

Set section properties:

设置截面属性

0 --

Automatically determine if pre-integrated section properties can be used (default)

自动计算是否能够提前积分截面属性。(默认)

1 --

Use numerical integration of section (required for birth/death functionality)

用户单元数值积分(在生/死功能的时候要求)

KEYOPT(12)

Tapered section treatment:

契型截面处理

0 --

Linear tapered section analysis; cross section properties are evaluated at each Gauss point (default). This is more accurate, but computationally intense.

线性变化的契型截面分析;截面属性在每个积分点计算(默认), 这种方法更加精确,但是计算量大

1 --

Average cross section analysis; for elements with tapered sections, cross

section properties are evaluated at the centroid only. This is an approximation of the order of the mesh size; however, it is faster.

平均截面分析;对于契型截面单元,截面属性仅仅在中点计算。近似于划分网格的阶数,特点是计算速度快

The solution output associated with these elements is in two forms:

这种单元用两种方式计算输出

Nodal displacements and reactions included in the overall nodal solution ? 节点位移和反应包括全部节点的计算。

? Additional element output as described in Table 188.1: \Output Definitions\

? 附加的单元输出在Table 188.1: \ 描述。

?

Where necessary, ANSYS recommends KEYOPT(8) = 2 and KEYOPT(9) = 2. See the ANSYS Basic Analysis Guide for ways to view results.

必要时,ansys 建议keyopt(8)=2 和keyopt(9)=2,参考ANSYS Basic Analysis Guide来找到查看结果的方法。

To view 3-D deformed shapes for BEAM188, issue an OUTRES,MISC or

OUTRES,ALL command for static or transient analyses. To view 3-D mode shapes for a modal or eigenvalue buckling analysis, you must expand the modes with element results calculation active (via the MXPAND command's Elcalc = YES option).

要看beam188 的3-D 变形形状,运用OUTRES,MISC 或者OUTRES 命令,所有的静态和
