Abstract: Two-level consistent secant operators are proposed for the nonlinear simulation of structures especially under cyclic loading. At the structural level, the quasi-Newton (Q-N) update of stiffness matrix is used to search ...

Abstract: Taking account of the spatial variation of material properties is of paramount importance to the safety and reliability evaluation of engineering structures. This necessitates the highly efficient and accurate representation ...

Abstract: Ethanol is considered a clean, cost-effective, carbon-neutral fuel. In this study, the effect of a surfactant (Span 80/Tween 80) and cosolvent (furan) on the macroscopic and microscopic mutual solubility characteristics ...
