Statyczne ciśnienie niszczące membranę z promieniowymi karbami

The theoretical model for evaluating bursting pressure for circular and quadratic squared membranes with small initial deflection and radial grooves is presented. The use is made of experimentally obtained nonlinear material characteristic and distortion energy theory. The effective stress concentration factor is developed on the basis of tension material tests. The results are compared with bursting pressures obtained experimentally by hydraulic method.
