Originální abstrakt

This paper focuses on assessment of probability of ceramic component fracture. The component is loaded by four point bending with different boundary conditions. The Weibull's weakest link theory, which includes the effect of first principal stress only, was chosen for calculation of probability of fracture. The stresses for calculations were evaluated numerically by finite element method. The component was discretizated by plane elements and constraints were considered in two variants. In the first variant, the constraints and loads are considered at the centerline of the rod (in accordance with rod theory). The second variant considers constraints and loads on the outer surface of the body. The contact between body and constraint (support) is considered in this variant. The influence of the radius of support on the value of probability of body fracture and the width of contact region is analyzed.
