VEXTEC Corporation was founded in 2000, with the goal of developing a computational process based in ICME (Integrated Computational Materials Engineering) to predict long-term product durability. This technology fills a gap in the existing capabilities provided by CAD/CAM, FEA, statistical modeling, and physical material and component testing, by effectively integrating them into a single computational processing framework.
What makes us different from other engineering consulting companies is our proprietary durability software, VPS-MICRO®, which we have been developing since VEXTEC’s founding. We have received over $25 million in development funding from the United States Department of Defense through its Small Business Innovative Research (SBIR/STTR) programs. During this time, VEXTEC has been granted seven patents related to our technology.
VEXTEC Corporation provides software, technical expertise and services in the areas of component, system, and fleet durability. We, in collaboration with our client companies, utilize our VPS-MICRO engineering software to help make better products and resolve in-service durability and reliability issues.
The insight VEXTEC’s software provides enables our clients to optimize their product design and manufacturing processes to achieve the desired product durability and life, while at the same time reducing product development time and cost. VEXTEC’s clients include leading multinationals in the aerospace, automotive, electronics, energy, heavy industry and medical device manufacturing sectors, as well as many federal government agencies.
Our initial research and development work took two distinct paths: the company’s material science experts focused on developing virtual material simulation, while our computational experts integrated our virtual material intellectual property with cloud computing to create a tool for analyzing component, system and fleet performance and assessing the impact on the client’s business. Various government agencies and Fortune 100 companies supported this important technology. As a result of its work and expertise in this field, the company was able to map material microstructure, the genetic code of materials. This mapping process can now be used to simulate manufactured product behavior by taking into account the variability imparted by the combination of material processing, geometric tolerances, and customer usage.
We model material at its fundamental level: its microstructure. Simulating microstructure is important since it plays the key role in determining when, where and how failures occur. Over the last 30 years, most engineering disciplines have embraced computational methods – CAD, CAE, EDA, CAM – that have dramatically increased manufacturing productivity. But the analysis of material failure remains largely wedded to old methods. Product reliability is determined using laboratory testing of many identical products. These methods are expensive and slow; worse, inaccuracies lead to overdesign with large safety factors. This overdesign leads to products that are bigger, heavier, more expensive and less competitive. Simulating product geometry and loads can be done with widely available tools such as CAD and FEA, but simulating a product’s material is difficult. Subtleties in casting, forging, rolling and heat treatments will vary the material microstructure widely. VLM allows manufacturers to predict product reliability with much less testing and greatly reduce costs.
Today, VEXTEC Corporation provides technical expertise and services in the area of component, system, and fleet durability and life. We utilize our Virtual Life Management® (VLM®) engineering software platform to help companies make better products and resolve in-service durability and reliability issues.
The VLM® simulation software platform meshes conventional FEA with a 3-D spatial model of the material microstructure to predict relative component durability and life over time. VEXTEC’s patented physics-based computational methods predict lifecycle data for each individual grain in the component’s material microstructure. The VEXTEC methodology has been successfully applied to metal, laminated composite, and hybrid composite structures.
VEXTEC provides insight into why damage occurs-how cracks and corrosion begin and grow over time. Sensitivity studies identify what can be done to prevent damage initiation and growth through modifications to material design, component design, processing, or in-service load conditions. These sensitivity studies can show the effects of varying attributes like heat treatments, surface conditions, alloys, geometry, residual stress, or in-service loads and stresses.
The insight VEXTEC provides enables our clients to optimize their product design and manufacturing processes to achieve the desired product durability and life, while at the same time reducing product development time and cost. VEXTEC’s clients include aerospace, automotive, electronics, energy, heavy industry and medical device manufacturing companies as well as many Federal government agencies.
VEXTEC Corporation has a comprehensive staff of engineering, scientific and software development, and business application specialists headquartered in Brentwood, TN, a suburb of Nashville. The company is privately held.
