由四根倾斜杆件和一个竖向杆件组成的平面桁架,在上部节点处施加竖向力和与平面外的力。 Assuming the large deformation analysis and neglecting the self-weight, determine the normal forces of the members and the out-of-plane displacement of the upper node.
本示例介绍由摩擦引起的不可逆过程。 After the loading and unloading, the end-point is in a different position than where it was at the beginning. Determine the movement of the node in the X direction.
