Analytical Study of a Circular Thin Plate Contacting with an Elastic Sphere
Applied Sciences, 2022 The problem that is addressed here is that of a circular thin plate clamped peripherally with frictionless contact to an elastic sphere. A complete and effective solution to this problem is developed to describe the relationship between the contact force

Large deformation and plates [PDF]
PAMM, 2012 AbstractIn the simulation of deformations of plates it is well known that we have to use a special treatment of the thickness dependence. Therewith we achieve a reduction of dimension from 3D to 2D. For linear elasticity and small deformations several techniques are well established to handle the reduction of dimension and achieve acceptable numerical ...
