The inplane Poisson's ratio represents the amount of transverse strain caused by an applied axial strain. In other words, it helps calculate how much a material will shrink in the direction perpendicular to the direction of stretching. Poisson's effect can be visualized easily by stretching a rubber band and observing how the thickness/width decreases. Inplane means that the stretching and consequent perpendicular shrinking are observed on the plane, or surface, of the composite plate or shell. Inplane Poisson's ratio can be predicted using different methods, with varying degree of complexity and accuracy. These methods can be accessed from this page, including:  Rule of mixtures (very good for predicting inplane Poisson's ratio)
 Periodic microstructure method (excellent for predicting all the elastic properties)
