WebMay 8, 2024 · A ‘plate’ is a thin, flat structural member subjected to loads that cause bending. Though, in reality, such a member is a three-dimensional body, analysis using the three-dimensional theory of elasticity is not essential if the thickness is small compared to the in-plane dimensions. Weba plate or shell are typically described in terms of either the small deflection Kirchhoff plate theory. However, real applications involve large deflections.
