Multi-scale Physics-Based Models for High Strength Titanium Alloys Accounting for Higher-Order Microstructure Statistics.

Phase 1 STTR

Institution: Louisiana State University

Agency: Air Force
Topic: AF09-BT29
Budget: 04/15/10 - 01/14/11
PI: Robert Lipton

The goal of this proposal is to demonstrate the feasibility of new multi-scale models for linking higher order micro-structure descriptions to failure initiation and crack propagation for high cycle fatigue of high strength titanium alloys. This includes new high temperature materials such as the lightweight intermetallic titanium aluminide tur...

Innovative Analysis Tool for Damage Growth From Loaded Composite Fastener Holes

Phase 1 SBIR

Agency: Navy
Topic: N092-095
Budget: 09/16/09 - 06/10/10
PI: Dr. Jim Lua

A software tool for residual strength and life prediction of composite bolted joints will be developed by enhancing and integrating an existing mesh independent delamination and matrix cracking network model in ABAQUS. The tool will be able to model arbitrary location, size of damage, and geometric configuration of a composite structure with fas...

Composite Damage Evaluation Tool

Phase 1 SBIR

Agency: Air Force
Topic: AF083-176
Budget: 12/12/08 - 11/19/09
PI: Dr. Jim Lua

The focus of the proposed effort is to develop a coupled composite damage assessment and repair evaluation tool for a given damage state measured by a NDI technique. New solution modules for damage and repair representation will be developed and linked with our existing mesh independent extended finite element (XFEM) toolkit for ABAQUS. This too...

Phase 1 SBIR

Agency: Air Force
Topic: AF06-092
Budget: 05/15/06 - 09/15/07
PI: Dr. Jim Lua

An automatic software tool for residual strength and life prediction of composite structure will be developed. This tool will for the first time be able to model arbitrary crack growth without user intervention or remeshing and thus provide a user-friendly, reliable tool for predicting component life. The automated delamination onset and growth ...
