Evaluation of the Rotation Capacity of Wide-Flange Beams Using Shell Finite Elements
Numerical simulation can be useful for planning of experimental tests, performance of parametric studies, and achieving an understanding of complex three-dimensional behavior that may...

Optimal Shape Design of Columns for Buckling
A procedure for the shape optimization of a column for prescribed buckling load is developed. The procedure uses a new analysis technique that enables the formulation of the optimization...

Original Formulation of the Finite Element Method
Following a brief summary of the 1952 state of the art of structural analysis, the paper describes the circumstances that led to the formulation of the finite element method by members...

Major Advances in Finite Element Model Technology
The evolution of finite elements is traced from the viewpoint of finite element shape functions and element-related techniques. Particular emphasis is placed on the isoparametric element,...

Extensions of Finite Element Technology for Automated Design
The finite element method, by itself, is an efficient analysis tool with which we can judge the quality of a proposed design. However, by coupling finite element analysis with numerical...

Getting Finite Element Programs to Reason About Their Analysis Assumptions
Despite the spectacular improvements of finite element analysis programs, there has been no corresponding progress in the development of physical modeling and interpretation aids. The...

Representation of Strategic Choices in Structural Modeling
A major concern in structural modeling is the proper choice of tools to achieve stated objectives. Problem statements in structural analysis and design are usually made in fairly abstract...

Idealized Models in Engineering Analysis
This paper examines the roles of idealization and discretization in engineering analysis and design. Physical idealizations as commonly used in analysis and design are non-analytic in...
