Item Визначення напружено-деформованого стану гумового буфера на основі уточненої моментної схеми скінченного елемента(Видавництво Львівської політехніки, 2013) Гребенюк, Сергій; Бова, ГаннаThis work is devoted to elaboration and numerical realization of method of research of the stressstrain state of the rubber buffer taking into account weak compressibility on the basis of the precise finite element moment scheme. To determine the stress-strain state of the rubber buffer in conditions of linear deformation the threedimensional finite element method has been used. For increasing the accuracy of numerical results the precise finite element moment scheme has been applied. This scheme is a modification of moment scheme and envisages the receipt of expressions for deformations on the base of supplement of approximating initial polynomials of finite elements to a complete. The undertaken research shows that calculation of rubber constructions taking into account weakly compressibility of materials allows getting the adequate results using the cubic approximation of displacements.
