Webblongitudinal stress varies through plate thickness and along the plate. This stress variation along the plate width due to stiffeners is also called shear lag effect. Actual stress distribution is rather complicated in the vicinity of stiffeners due to 3D stress condition resulting from plate bending with stiffeners between end supports and ... WebbThe classical plate equation arises from a combination of four distinct subsets of plate theory: the kinematic, constitutive, force resultant, and equilibrium equations. where w0 is the displacement of the middle plane in z direction. To relate the plate's out-of-plane displacement w0 to its pressure loading pz, we combine the results of the ... WebbCauchy (1828) and Poisson (1829) developed the problem of plate bending using general theory of elasticity. Then, in 1829, Poisson successfully expanded “the Germain-Lagrange plate equation to the solution of a plate under static loading. In this solution, however, the plate flexural rigidity D was set equal to a constant term” (Ventsel and treesize portable free download
