Adaptive Methods
The objective is to improve the reliability of mathematical models of structural and mechanical systems. Methods for efficient control of the errors of idealization and discretization are under development. [Professor Szabo]

Criteria for Failure Initiation
Advanced extraction methods for the computation of generalized stress intensity factors from finite element solutions are being developed. [Professor Szabo]

Dimensional Reduction
Hierarchic models for structural plates and shells are being developed. The problem of modelling laminated plates is of particular interest. [Professor Szabo]

Research in Finite Element Analysis
Emphasis is on the following areas: elastostatic problems, p and h-p extensions, error estimation, advanced methods for the computation of engineering data from finite element solutions. Investigation of procedures for the control of errors of idealization. Analysis of plates and shells. Structural stability problems. Methods of analysis of fastened connections, with particular reference to aircraft structures. [Professor Szabo]

Rotor Wake Modeling
During the flight of airplane propellers, helicopters, and tilt rotors, the rotor wake undergoes important dynamic motions that profoundly influence vehicle dynamics. This project seeks to correctly model this behavior. [Professor Peters]

Structural Connections
Reliable methods for the numerical simulation of fastened structural connections, with particular reference to aircraft structures, are under development.
