METHOD AND SYSTEM FOR DETERMINING FIELD QUANTITIES IN A STRUCTURAL JOINT

摘要

A Macroscopic Bonded Joint Finite Element (MBJFE) is capable of predicting field quantities in a bonded zone of a structural joint using a limited number of degrees of freedom. The MBJFE embeds an analytical solution directly within the element. Its stiffness and load response are based on non-linear shape functions that are dependent on load character. All critical terms are formulated as functions of a dimensionless mechanical load fraction allowing for solution via an iterative, non-linear finite element solver. The MBJFE is internally adaptive to internal and external conditions such as instantaneous external loads or internal temperatures.
