TL;DR: On August 24, 2006, the Standard Performance Evaluation Corporation (SPEC) announced CPU2006, which replaces CPU2000, and the SPEC CPU benchmarks are widely used in both industry and academia.
Abstract: On August 24, 2006, the Standard Performance Evaluation Corporation (SPEC) announced CPU2006 [2], which replaces CPU2000. The SPEC CPU benchmarks are widely used in both industry and academia [3].

TL;DR: Sequence diagrams document the interoperability of the analysis classes for solving nonlinear finite-element equations, demonstrating that object composition with design patterns provides a general approach to developing and refactoring nonlinear infinite-element software.
Abstract: Object composition offers significant advantages over class inheritance to develop a flexible software architecture for finite-element analysis. Using this approach, separate classes encapsulate fu...

TL;DR: A new plastic hinge integration method overcomes the problems with nonobjective response caused by strain-softening behavior in force-based beam-column finite elements by using the common concept of a plastic hinge length in a numerically consistent manner.
Abstract: A new plastic hinge integration method overcomes the problems with nonobjective response caused by strain-softening behavior in force-based beam-column finite elements. The integration method uses the common concept of a plastic hinge length in a numerically consistent manner. The method, derived from the Gauss-Radau quadrature rule, integrates deformations over specified plastic hinge lengths at the ends of the beam-column element, and it has the desirable property that it reduces to the exact solution for linear problems. Numerical examples show the effect of plastic hinge integration on the response of force-based beam-column elements for both strain-hardening and strain-softening section behavior in the plastic hinge regions. The incorporation of a plastic hinge length in the element integration method ensures objective element and section response, which is important for strain-softening behavior in reinforced concrete structures. Plastic rotations are defined in a consistent manner and clearly related to deformations in the plastic hinges.
