Тест 7.4 Contact problem for a cylinder

Numerical solution: P. Panagiotopoulos Inequalities in Mechanics and their Applications, Moscow: Mir, 1989,. 387.

Geometry::

r = 1.315 м; h = 0.04 м.

Material characteristics: Е=6 х 10⁴ т/м², ν=0.3, one-way rigidity EF/l = 10⁶ т/м.

Boundary conditions: Radial movements outward are prohibited

Loads: External pressure varies in depth z, 0<z<2r, by the linear lawу Fr = 0.58(1.18+z) т/м2.
