MODELING OF THE AGING OF A COMPONENT COMPOSED OF A NONLINEARLY ELASTIC MATERIAL UNDER LOAD

摘要

The invention relates to a method for the computational modeling of the aging of a component composed of a nonlinearly elastic material under a specified load and is characterized in that the unloaded component (1) is replaced with a plurality of node points (3) in the model, which node points are connected among each other by a plurality of bars (2), wherein a mathematical material model is imposed on each bar (2) and the bars form a first mesh; the component (1) is deformed in the model in accordance with the real load and additional bars (4) are inserted between the node points (3) in this deformed state, wherein the additional bars (4) form a second mesh, while bars (2) of the first mesh are deleted; and the extent of the interconnection of the second mesh is made dependent on the duration of the deformed state.
