Linearized Stress
线性应力
It is customary in beam design to employ components of axial stress that contribute to axial loads and bending in each direction separately. Therefore, BEAM188 provides a linearized stress output as part of its SMISC output record, as indicated in the following definitions:
对于梁设计很常规的轴力由轴向荷载和在各个端点的弯曲独立提供。因此，beam188 提供线性的应力输出作为它的SMISC 输出命令的一部分，由下面的定义来指示：
SDIR is the stress component due to axial load.
SDIR 是轴力引起的应力分量。
SDIR = FX/A, where FX is the axial load (SMISC quantities 1 and 14) and A is the area of the cross section.
SDIR＝FX/A，FX 是轴力（SMISC 的数值为1 和14），A 表示截面面积。
SBYT and SBYB are bending stress components.
SBYT 和SBYB 是弯曲应力分量。
SBYT = -MZ * ymax / Izz SBYB = -MZ * ymin / Izz SBZT = MY * zmax / Iyy SBZB = MY * zmin / Iyy
where MY, MZ are bending moments (SMISC quantities 2,15,3,16). Coordinates ymax, ymin, zmax, and zmin are the maximum and minimum y, z coordinates in the cross
section measured from the centroid. Values Iyy and Izz are moments of inertia of the cross section. Except for the ASEC type of beam cross section, ANSYS uses the maximum and minimum cross section dimensions. For the ASEC type of cross section, the maximum and minimum in each of Y and Z direction is assumed to be +0.5 to -0.5, respectively.
这里MY、MZ 是弯距（SMISC 数值是2、15、3、16）。坐标ymax, ymin, zmax, 和 zmin 是y 和z 坐标的最大和最小值。Iyy 和Izz 是截面惯性距。对于ASEC 梁截面，ANSYS 用最大和最小截面尺度，对于ASEC 种类的截面，最大最小的Y 和Z 方向直接分别假定在+0.5 到-0.5。
Corresponding definitions for the component strains are:
单元应力的相应定义
EPELDIR = EX EPELBYT = -KZ * ymax EPELBYB = -KZ * ymin EPELBZT = KY * zmax EPELBZB = KY * zmin
where EX, KY, and KZ are generalized strains and curvatures (SMISC quantities 7,8,9, 20,21 and 22).
这里EX、KY 和KZ 是总应力和曲率（SMISC 数值是7,8,9, 20,21 和22）
The reported stresses are strictly valid only for elastic behavior of members.
BEAM188 always employs combined stresses in order to support nonlinear material behavior. When the elements are associated with nonlinear materials, the component stresses may at best be regarded as linearized approximations and should be interpreted with caution.
输出的应力仅仅对于单元的弹性行为有效。Beam188 总是组合应力来支持非线性材料的行为。当单元和非线性材料相关的时候，组合应力最好作为线性近似来对待，应该谨慎的说明。
The Element Output Definitions table uses the following notation:

A colon (:) in the Name column indicates the item can be accessed by the Component Name method [ETABLE, ESOL]. The O column indicates the availability of the items in the file Jobname.OUT. The R column indicates the availability of the items in the results file.
name 列表示该项目可以通过构成名字的方法来获得[ETABLE, ESOL]。第O 列表示该项有效的说明在文件Jobname.OUT 中。R 列表示该项的结果显示在results 文件中。
In either the O or R columns, Y indicates that the item is always available, a number refers to a table footnote that describes when the item is conditionally available, and a - indicates that the item is not available.
无论在0 还是R 列中，Y 表示该项一直是可用的。数值表示描述哪里该项是选择性提供的脚注，－表示该项不提供。
