E-MAIL: shyner@pkwsmtp.wpafb.af.mil, shyner@pkwsmtp.wpafb.af.mil. Background "This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; proposals are being requested and a written solicitation will not be issued. This solicitation is issued as a Request for Quotation (RFQ). The solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular 90-46. This is a sole source requirement IAW FAR 6.302-1. This RFQ has the following line item: Zencrack Unix SGI Version Software Program. This shall include three years of software maintenance. Zencrack is a software program that enables us to perform analysis on cracked structures. The capability provided with Zencrack allows us to include crack geometry in complex 3-D structures under complex load (thermal and mechanical) conditions with multi-axial material properties. If required, Zencrack also has the ability to assess the crack growth under time varying load conditions. Zencrack interfaces with one of the leading developers of structural analysis software, Abaqus. Requirements of the software program is as follows: A) Generate cracked component meshes in preparation for finite element analysis B) Analyze a cracked component C) Predict crack growth within a component (without any user intervention to control the analysis) D) Analyze one or more cracks in a model E) Initial crack size and location as defined by the user, including embedded cracks F) Automatic generation and processing of aspects of the analysis specifically related to fracture mechanics (stress intensity factor, energy release rate, crack growth rate) G) Simulation of crack growth under fatigue or sustained loading H) Crack growth dependent on loading and geometry not predetermined paths I) Capabilities for linear or non-linear stress analysis, heat transfer, sequential thermal stress or fully coupled thermal stress analysis J) Ability to analyze cracks in components with temperature dependent material properties K) Ability to use isotropic or orthotropic materials data L) Ability to interpolate temperature data from an uncracked mesh to a cracked mesh Delivery required by 1 Oct 99. FOB Destination. Net 30 terms. The following clauses and provisions apply: 52.212-1, 52.212-2(a) and 52.212-3. Clause 52.212-4 and 52.212-5 shall be included with any offer. Ship to: ASC/ENFP, 2530 Loop Road West, Bldg 560, Area B, Wright-Patterson AFB OH 45433-7101 Wright-Patterson Air Force Base intends to award to Zentech Incorporated, 8582 Kaly Freeway, Suite 205, Houston, Texas 77024. Authority: 10 U.S.C. 2304?
