  • Computer process for prescribing an assembly load to provide pre-tensioning simulation in the design analysis of load-bearing structures
    Patent number: 5920491
    Abstract: A computer implemented process simulates the application of a tension force in an element of an assembly. The process defines a finite element model for the element, and creates a pre-tension surface in the finite element model of the element for applying the tension force. Conditions are prescribed relative to the pre-tension surface for applying the tension force in the simulation. The conditions include prescribing an assembly load including either a tension force or tightening adjustment. The assembly load is then applied to the pre-tension surface of the element to simulate the tension in the element of the assembly. The results of the simulation are then evaluated for structural integrity, and subsequent structural redesign of the element is performed when necessary.
