A New Stress Based Approach for Nonlinear Finite Element Analysis

This article demonstrates a new approach for nonlinear finite element analysis. The methodology is very suitable and gives very accurate results in linear as well as in nonlinear range of the material behavior. Proposed methodology can be regarded as stress based finite element analysis as it is required to define the stress distribution within the structural body with structural idealization a...

Finite Element Studies in the Out-Of-Plane Failure of Unreinfored Masonry

This paper describes finite element studies of one-way out-of-plane failure of unreinforced masonry walls under static loading. The studies are early steps in the development of a method that will be applicable to two-way out-of-plane failure of walls under dynamic loading. The approach is based on a discrete-crack approach, where mortar beds are modelled using contact-interface elements, and m...

Finite Element Analysis for CFST Columns under Blast Loading

The columns of frame structures are the key load-bearing components and the exterior columns are susceptible to attack in terrorist blasts. When subjected to blast loads, the columns would suffer a loss of bearing capacity to a certain extent due to the damage imparted which may lead to their collapse and even cause the progressive collapse of the whole structure . The concrete-filled steel col...

A Hybrid Stress Plane Element with Strain Field

In this paper, a plane quadrilateral element with rotational degrees of freedom is developed. Present formulation is based on a hybrid functional with independent boundary displacement and internal optimum strain field. All the optimality constraints, including being rotational invariant, omitting the parasitic shear error and satisfying Fliepa’s pure bending test, are considered. Moreover, the...
