1. A method for the computer implemented simulation of mechanical deformation on a mechanical structure, in which the mechanical structure is defined according to a model comprising a grid of the mechanical structure with grid nodes defining grid elements, a result of the simulation of the mechanical deformation of the mechanical structure is obtained, the result comprising a deformed model of the mechanical structure, the deformed model deformed by the simulation of the mechanical deformation, and the method comprises the steps of:
defining at least one simulated strain gauge between a first starting position and a second starting position with respect to the model, and for each starting position:
selecting a grid element of the model,projecting each starting position onto a selected grid element,determining, based on the mechanical deformation simulation result, a position of the projection of each starting position onto the deformed grid element,at the position of the projection, applying an inverse transform to the projection in order to obtain an arrival position, and calculating a first distance between the first starting position and the second starting position, calculating a second distance between a first arrival position obtained for the first starting position and a second arrival position obtained for the second starting position, and calculating a deformation associated with the at least one simulated strain gauge, based on the first distance and the second distance. |
