Thermal Stress Analysis of Free-Free Trusses under Temperature Change Using a Self-Regularized Approach

Abstract

AbstractIn this study, a self-regularized approach was employed to determine the thermal stress in a free-free truss, which results in a singular stiffness matrix. Physically, the stiffness and flexibility matrices of structure with proper constraints are ...Practical ApplicationsIn engineering applications, the self-regularization approach provides a systematic and straightforward method for structural analysis, particularly for free-free structures. In addition, our approach is more stable than the Moore–...
