The .strs file is an OptiStruct ASCII format results file.

File Creation

This file is created when the OPTI, OS or BOTH formats are chosen. (See documentation for the I/O Option OUTPUT).

Description

Stress

Stress results from linear static analysis. Output is controlled by the I/O Option STRESS (or ELSTRESS).

File Format

The stress file has the following format:

For each iteration, the following header is used:


iter

Iteration

Numlds

where:


iter

is a keyword denoting the beginning of a new iteration.

Iteration

is the Iteration number.

Numlds

is the number of load cases for which this output is created.


Each iteration section is divided up by subcase. Output for each subcase starts with a line in the following format:


Id

Number_of_els

STRS:Spc_id(Datatype)

where:


Id

is the output identification number for the subcase. This is not the same as the subcase ID used in the input data.

Number_of_els

is the number of elements for which this output is requested.

STRS

is a fixed keyword.

Spc_id

is the SID for SPC's referenced by this subcase.

Datatype

is a keyword indicating the type of subcase involved.

(LOAD) declares data is for a linear static subcase.


Stress information is then provided, for each element, in the following format:

 

EID

Stress1

Stress2

Stress3

Stress4

Stress5

Stress6

Stress7

Stress8

Stress9

where:

 

EID

Element identification number.

Stress1

von Mises stress for 2D and 3D elements, Maximum Axial stress for 1D elements, or maximum stress in CWELD elements.

Stress2

Normal X-stress at Z1 for 2D elements, Normal X-stress for 3D elements, or Axial stress for 1D elements.

For BAR/BEAM it is the stress at C at end A. Axial Stress for CWELD elements.

Stress3

Normal X-stress at Z2 for 2D elements, Normal Y-stress for 3D elements, or Axial stress for 1D elements.

For BAR/BEAM it is the stress at D at end A. Maximum tensile stress at end A for CWELD elements.

Stress4

Normal Y-stress at Z1 for 2D elements, Normal Z-stress for 3D elements, or Axial stress for 1D elements.

For BAR/BEAM it is the stress at E at end A. Minimum tensile stress at end A for CWELD elements.

Stress5

Normal Y-stress at Z2 for 2D elements, Shear XY-stress for 3D elements, or Axial stress for 1D elements.

For BAR/BEAM it is the stress at F at end A. Maximum tensile stress at end B for CWELD elements.

Stress6

Shear XY-stress at Z1 for 2D elements, Shear YZ-stress for 3D elements, or Axial stress for 1D elements.

For BAR/BEAM it is the stress at C at end B. Minimum tensile stress at end B for CWELD elements.

Stress7

Shear XY-stress at Z2 for 2D elements, Shear XZ-stress for 3D elements, or Axial stress for 1D elements.

For BAR/BEAM it is the stress at D at end B. Maximum shear stress for CWELD elements.

Stress8

Maximum shear stress for CWELD elements.

For BAR/BEAM it is the stress at E at end B. Bearing stress for CWELD elements.

Stress9

Bearing stress for CWELD elements.

For BAR/BEAM it is the stress at F at end B.
