Un cable muy rígido está suspendido entre dos apoyos. Determine the equilibrium shape of the cable (the catenary), consider the gravitational acceleration, and neglect the stiffness of the cable. Verify the position of the cable at the given test points.
El objetivo de este ejemplo es demostrar un proceso irreversible causado por la fricción. 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.
Un recipiente de paredes gruesas está cargado por una presión interna tal que el recipiente alcanza un estado elástico-plástico. While neglecting self‑weight, the analytical and numerical solutions for the radial position of the plastic zone border (under the Tresca hypothesis) are determined and compared.
