Expert Like System for Cylindrical Shell Support
The submitted contribution describes expert-like SAUDES program system based on data base of 288 cases of contact problem solutions. The data base consists of extreme values of longitudinal and circumferential stresses at the saddle horn. These values are functions of 3 parameters that are shell geometry, dimensions of loaded area and non-dimensional distance of saddle from stiffening element (plate, rib or drumhead). The solution is based on semibending shell theory for semi-infinite length of cylindrical shell, for line load contact forces. Both ends influence is done as superposition of two single side influence. The basis of task is 3-dimensional linear interpolation of 3-parameters function. The stresses obtained are evaluated by help of ASME stress categorisation. The procedure suggested is compared with six examples of theoretical and experimental solutions, known from technical literature.
