SYSTEM AND METHOD FOR CALCULATING STRUCTURAL STRESS |
| 摘要 |
A system is disclosed for computing structural stress using higher order finite elements. The system may include a weld grouping engine configured to define a group of weld line nodes and a group of weld line elements corresponding to a weld line representing a welded joint, and a spatial search engine configured to detect a plurality of segments between the weld line nodes. The system may also include a structural stress calculation engine configured to retrieve nodal force data of the group of weld line nodes, calculate a sum of nodal forces and a sum of nodal moments for each segment based on the retrieved nodal force data, and calculate a structural stress for each segment based on the sum of nodal forces and the sum of nodal moments calculated for the segment. |

1. A system for analyzing structural stress of a structure, the system comprising:
a weld grouping engine configured to define a group of weld line nodes and a group of weld line elements corresponding to a weld line representing a welded joint; a spatial search engine configured to detect a plurality of segments between the weld line nodes; and a structural stress calculation engine configured to:
retrieve nodal force data of the group of weld line nodes;calculate a sum of nodal forces and a sum of nodal moments for each segment based on the retrieved nodal force data; andcalculate a structural stress for each segment based on the sum of nodal forces and the sum of nodal moments calculated for the segment. |
