Description

The parallel directions in sample and crystal axis is taken as input in the program.

  1. This program calculates the Coordinate transformation matrix between two given reference frames.
  2. the transformation matrix is obtained as MatB-J-MatA (GRAIN J SAMPLE).
  3. This way orientations relationship matrix in a poly crystalmaterial can obtained which has a bias for example Cu or Cube texture.

Inputs when running the program

INPUT direction of crystal A (sample axis):
1 0 0
INPUT direction of crystal B (crystal axis) which is parallel to A:
0 0 1
INPUT direction of crystal A (sample axis):
0 0 1
INPUT direction of crystal B (crystal axis) which is parallel to A:
1 0 0
INPUT number of grains
500
Which pole you want to print: 100, 110 or 111
100
WHICH HEMISPHERE: UPPER = 1 LOWER = 0 BOTH = 2
0

Name

trans_plast_tensor.for

This is a source code of this program. For the execution, it needs to be compiled.
