`block.zone.plane.traction`

Syntax

- v = block.zone.plane.traction(bzp,v<,a>)
Get the traction on the plane normal to the vector v. If the optional argument arr is given, arr is filled with the normal and shear stress on the plane normal to v. arr(1) is given the normal stress, arr(2) is given the maximum shear stress, and arr(3) to arr(5) is filled with the (\(x\), \(y\), \(z\)) components of the shear stress direction.

Returns: v - traction on the plane Arguments: bzp - block zone pointer

v - normal to the plane

a - array containing five elements that specify: normal stress, shear stress, and the \(x\),`y`, and \(z\) components of the shear stress direction, respectively.
