Phase 2 SBIR

Agency: National Aeronautics and Space Administration
Topic: 10-2-A1.12
Budget: 01/01/12 - 12/31/12

A Probabilistic Fatigue Damage Assessment Network (PFDAN) toolkit for Abaqus will be developed for probabilistic life management of a laminated composite structure with both microcracking induced stiffness degradation and cyclic loading induced delamination crack growth without remeshing. It is based on a high fidelity Fatigue Damage Assessment...

Phase 2 SBIR

Agency: Air Force
Topic: AF103-005
Budget: 10/19/11 - 10/19/13

ABSTRACT: A Hybrid Structure Evaluation and Fatigue Damage Assessment (HYSEFDA) toolkit for Abaqus will be developed for advanced hybrid structures under multi-axial and variable amplitude cyclic loading. The tool will be able to characterize arbitrary geometric configurations of fiber metal laminates with the coexistence of multiple metal ply a...

Phase 2 STTR

Institution: University of Texas at El Paso

Agency: Navy
Topic: N10A-T041
Budget: 08/23/11 - 02/23/13
PI: Unavailable

A software toolkit for Abaqus (XSHELL) will be developed for fracture evaluation and load deflection prediction of welded aluminum ship structures subjected to impulsive loading. The mesh independent crack description and fracture energy dissipation will be achieved in XSHELL through the implementation of two overlay elements with an embedded co...

Phase 2 SBIR

Agency: Navy
Topic: N092-095
Budget: 03/23/11 - 03/23/12

Global Engineering and Materials, Inc. (GEM) along with its team members, University of Dayton Research Institute (UDRI), Lockheed Martin (LM) Aero, and Sikorsky Aircraft will develop an add-on toolkit for Abaqus with high fidelity prediction of residual strength and life of laminated composite structures with fastener holes. A discrete crack ne...

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 10-1-A1.12
Budget: 01/01/11 - 12/31/11

A composite fatigue damage assessment and risk informed prognosis toolkit will be developed by enhancing and integrating existing solution modules within a probabilistic analysis framework. This tool will for the first time be able to address concurrently both microcracking induced stiffness degradation and cyclic loading induced delamination cr...

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 10-1-A1.03
Budget: 01/01/11 - 12/31/11

Global Engineering and Materials, Inc. (GEM) along with its team members, Clarkson University and LM Aero, propose to develop a mesh independent probabilistic residual life prediction tool for metallic airframe structures. The deterministic solver of this probabilistic analysis tool will be developed by integrating our cutting edge extended fini...

Phase 1 SBIR

Agency: Air Force
Topic: AF103-005
Budget: 12/08/10 - 09/10/11

A software tool for residual strength and life prediction of advanced hybrid structures will be developed by enhancing and integrating an existing mesh independent 3D X-FEM solid element with a partially bonded cohesive interface element in Abaqus. The tool will be able to model arbitrary location, size of damage, and geometric configuration of ...

Phase 1 SBIR

Agency: Navy
Topic: N102-173
Budget: 10/18/10 - 08/17/11

A fully coupled fire-structure interaction module will be developed and implemented within GEM s Abaqus Fire Interface Simulator Toolkit (AFIST) for fire response prediction in aluminum ship structures. This enhanced AFIST will be able to characterize a 3D complex geometry where its topology is not in conformation with a rectilinear CFD grid. Gi...

Phase 1 SBIR

Agency: Navy
Topic: N102-173
Budget: 10/18/10 - 08/17/11

A 3D non-linear and rate-dependent constitutive model will be developed and implemented within GEM s Abaqus Fire Interface Simulator Toolkit (AFIST) to characterize the time-, stress-, and temperature-dependent material response of aluminum alloys. Both the material and geometric non-linearities will be characterized based on Abaqus kinematic d...

Phase 1 STTR

Institution: University of Texas at El Paso

Agency: Navy
Topic: N10A-T041
Budget: 06/28/10 - 08/19/11

A software tool for fracture evaluation and load deflection prediction of welded aluminum ship structures subjected to impulsive loading will be developed by enhancing and integrating an existing extended finite element method (XFEM) for dynamic fracture of thin shells in Abaqus. The software package will be able to model arbitrary crack paths a...
