Data Driven with Lou Peck

Terry Day is the founder of Engineering Dynamics Corporation (EDC) and the creator of HVE, EDCRASH, EDSMAC, and SIMON. A native of Coos Bay, Oregon, he earned two mechanical engineering degrees from Oregon State and a master’s from the University of Michigan’s Highway Safety Research Institute, where he studied the NHTSA-funded CRASH, SMAC, and HVOSM mainframe codes. After starting his career in failure analysis and accident reconstruction in Portland, he founded EDC in 1982 to bring those programs to the IBM PC, releasing EDCRASH in 1984, and later led the five-year development of HVE and the creation of SIMON and the DyMESH 3D collision model. A licensed professional engineer, Terry handed leadership of EDC to Tony Cornetto in 2019 but still teaches EDC’s reconstruction and simulation courses every year, as he has since the mid-1980s, along with the 3D physics workshops at the HVE Forum.You can watch the podcast and find links from the show here.--Timeline of Topics00:00:00 - Teaching by Hand and Knowing Your Software00:03:18 - Early Life, Education, and Graduate School at Michigan00:12:07 - NHTSA and the Origins of SMAC and CRASH00:28:39 - From Mainframes to the PC and Founding EDC00:54:39 - Early Customers, Manuals, and Building Credibility01:10:43 - Developing HVE, SIMON, and DyMESH01:40:20 - The Simulation Workflow and What Makes a Good Match02:00:44 - Model Selection, Parameters, and Testifying to a Range02:19:28 - The Future: Tire Models and AI02:27:28 - Retirement, Succession, and Advice for Young Recons
