Abstract: A novel least-squares implementation of the finite-element method is presented to evaluate stream functions in the solution of field problems. The method is programmatically similar to the solution of the Laplace equation, ...

Abstract: A formulation of the theory of plasticity in the strain space, which is a special case of the theory developed by Naghdi and coworkers, is presented here. A method to develop hardening functions to treat softening materials ...

Abstract: This study presents a self-consolidating concrete mix developed for thin wall construction. Casting of vertical thin concrete walls requires a stable, pumpable, and highly flowable mix. The developed mix has increased ...

Abstract: A numerical method to calculate the load-settlement of an axially loaded pile is presented. The method is based on an iterative scheme that tests the global equilibrium conditions and the load transfer (t-z) equations. The ...

Abstract: This paper presents a theoretical and computational framework for the analysis of structures that are subjected to inelastic static or dynamic overloads. Current practice in structural engineering assumes elastic material ...

Abstract: In this study, a set of rules is established that, when used in the modeling of dilatant soils, within the framework of associative plasticity, enables very successful shear and dilatancy predictions. The most important ...

Abstract: In this work, the plane strain pressuremeter test is examined using a finite strain elasto-plastic analysis. The pressure-meter expansion is analyzed as a finite strain problem using a Lagrangian formulation employing the ...

Abstract: The finite element method is used to solve contact problems. The approach is general and is used to solve contact problems between flexible bodies. A system of constitutive relations which are applicable to elasto‐plastic ...

Abstract: A truss-based simulation of reinforced concrete columns under compression is presented in this study. The concrete truss elements are modeled based on advanced constitutive equations that take into consideration confinement ...

Abstract: The effectiveness of internal curing of high-strength self-consolidating concrete (SCC) using saturated recycled-concrete aggregates is examined in this study. Tests were performed on SCC using natural rock aggregate ...
