Purpose

To include Poisson's ratio effects in an analysis.

Theory

Refer to Poissons Ratio for further information on this feature.

Keyword Format

A block of two lines which define the Poisson’s Ratio for all or selected elements (in terms of element sets). If values are defined for individual elements sets, the block of lines can be repeated as often as necessary.

SET=Set Name

Poisson's Ratio

Table Input

Input:	Description
Element Set:	The element set to which Poisson’s ratio applies. This defaults to All, to indicate all elements.
Poisson's Ratio:	The value of Poisson's ratio. This defaults to a value of 0.

Notes

(a)By default, Poisson's ratio effects are not included in the analysis. If included, axial changes due to Poisson's ratio and internal and external pressure are calculated.
