摘要： The invention relates to a method for designing the wall thickness of permanently statically and/or dynamically loaded components, wherein the components are produced from a fiber-reinforced polymer material. In a first step, the orientation of the fibers in fiber-reinforced plastic and the location of the joint lines in the component are determined by a first simulation calculation. A utilization factor of the strength of the component is calculated in a second simulation calculation. The wall thickness of the component is adapted to the result of the second simulation calculation, and the previous steps are repeated if the wall thickness is subjected to change. The invention further relates to a component made of a fiber-reinforced polymer material having a wall thickness designed by the method according to the invention.

摘要： The invention relates to a structure for absorbing the energy of impacts thereto, wherein the structure (1) is able to deform plastically from an impact and optionally can be at least partially destroyed, wherein at least one of the following features is guaranteed: a) the structure (1) comprises stiffening ribs (7), wherein the ribs (7) are disposed at an angle (α) with respect to the axial direction and are positioned relative to one another such that when a rib (7) fails, a force acting on the structure (1) in the axial direction is absorbed by another rib (7), b) the structure (1) comprises ribs (13) running in the axial direction, wherein the ribs (13) run substantially in a wave-like or zigzag pattern, c) the structure (1) comprises at least one rib (15) that runs in a first plane in the axial direction and that is connected to at least two ribs (11) running in the axial direction in a second plane that is rotated with respect to the first plane, d) the structure (1) comprises at least two layers (23, 27, 33) in the direction of impact, each of which exhibits different resiliency characteristics and different failure behavior.
