Abstract : V-LAB is a Window's-based analysis tool for structural integrity assessment of composite components. The software allows failure investigators to work within 'virtual laboratories' representing different structural levels within a composite component. Data can be exchanged seamlessly between the different labs, allowing results to be easily integrated. A prototype of the V-LAB software system was developed with labs for micromechanics analysis, material definition, and failure analysis of composite laminates and thin-walled beams. V-LAB provides a general software framework where independent analysis modules can be coupled for structural analysis. A relational database was developed containing all required data for the various analyses. The independent modules can share information via the database, and new modules can be added to V-LAB. Access is provided to existing material databases and analysis functions, simplifying development of new modules. This research demonstrated the potential to develop an easy-to-use, integrated analysis environment that meets the Air Force's need to perform efficient, independent failure analyses. Due to the flexible, extendible nature of the program, V-LAB can be easily adapted for use by civilian agencies and industries involved in design and failure analysis of composite components.
