Mr. Nauman Sheikh is an Assistant Research Engineer in the Roadside Safety Program at TTI. He is a licensed Professional Engineer with the state of Texas (No. 105155). Mr. Sheikh is specialized in the field of roadside safety and computational mechanics. He is actively involved in the design and evaluation of roadside safety appurtenances using non-linear dynamic finite element modeling and simulation.
Mr. Sheikh has served as principal investigator and co-principal investigator on various research studies sponsored by various DOT's and research agencies. He has contributed to design and analysis of several roadside safety appurtenances including concrete median barrier systems, metal guardrails, bridge rails, work-zone barriers, guardrail end treatments, and energy absorbing crash cushions. Mr. Sheikh has extensive experience in modeling and validation of LS-DYNA finite element models involving full-scale vehicular impacts with roadside safety appurtenances. He is also experienced in using the multi-rigid body vehicle dynamics packages (such as Carsim and MSC-ADAMS) for analysis of a wide range of vehicle types for a variety of different roadway/roadside and encroachment conditions. Some of the recent projects include development of national guidelines (NCHRP Report 554) for applying aesthetic surface treatments to concrete barriers. Mr. Sheikh has also recently developed a new anchored temporary concrete barrier with limited deflections for the WS-DOT pooled fund states. He has also actively contributed to design and development of new barrier connections for Texas and Montana DOT's portable concrete barriers through finite element analysis and testing. Mr. Sheikh has also worked on the development of a new and reusable Hybrid Energy Absorbing Reusable Terminal (HEART) crash cushion. Currently Mr. Sheikh is working on an NCHRP project (16-05) for evaluating and mitigating crashes resulting from roadside ditches.
Mr. Sheikh has a wide range of experience in the field of numerical computational mechanics based on sound academic background. He has participated in several workshops pertaining to the modeling and simulation techniques using LS-DYNA, Carsim, ADAMS, and other commercial packages. Mr. Sheikh has also worked on the use of meshless methods for numerical solutions to problems in mechanics. This was the focus of Mr. Sheikh's graduate research.
