WebJan 1, 2024 · This leads to the wider class of Cosserat-type or micro-polar type theories which introduce intrinsic length scales via higher order gradients or additional degrees of freedom (Cosserat and Cosserat [3], Nowacki [4] and Maugin and Metrikine [5]). In a physical sense, each point of the material could be asymptotically equivalent to a rigid body. WebHere we firstly present two sets of plate equations of the Cosserat type. The first set is introduced by the direct approach, while the second is based on the three- dimensional equations of the Cosserat continuum and a …
WebMay 11, 2011 · This material model grasps direct coupling between the Cauchy-type and Cosserat-type (or micropolar) effects in Hooke's law. An identical strategy of invariance is set for both problems, leading to a remarkable similarity in their results. For both problems, the planar components of stress and couple-stress undergo strong invariance, while ...
