Pmma poisson ratio
WebPoisson's ratio. The Poisson's ratio is the ratio of the relative strain contraction (or transverse strain) normal to the applied load - to the relative extension strain (or axial stress) in the direction of the applied load. The Poisson's coefficient can be expressed as: μ = - et / el (1) where. Poisson relation μ =. et = transverse deformation. http://www-mdp.eng.cam.ac.uk/web/library/enginfo/cueddatabooks/materials.pdf
