На обоих концах затем закреплен трехмерный блок из упруго-пластического материала. The block's middle plane is subjected to a pressure load. The surface plasticity is described according to the Tsai-Wu plasticity theory.
Теперь можно определить максимальный прогиб трехмерного блока, защемленного на обоих концах. The block is divided in the middle: the upper half is made of an elastic material and the lower part is made of timber - an elasto-plastic othotropic material with the yield surface described according to the Tsai-Wu plasticity theory. The block's middle plane is subjected to vertical pressure.
Определите максимальный прогиб четырех колонн, закрепленных снизу и соединенных жестким блоком сверху. The block is loaded by pressure and modeled by an elastic material with a high modulus of elasticity. The outer columns are modeled as orthotropic elastic material, and the inner columns as orthotropic elastic-plastic material with the same elastic parameters as the outer columns and plasticity properties defined according to the Tsai-Wu plasticity theory.
Деревянная балка, усиленная на концах двумя стальными пластинами, подвергается нагрузке давления. The wood fibers are parallel to the upper loaded side of the beam. The plastic surface is described according to the Tsai-Wu plasticity theory.
