EDUCATION:

Ph.D. Eng. – 1992 Probabilistic Finite Element Analysis, University of Michigan, Ann Arbor. M.S. Eng. – 1988 Structural Engineering, Ecole Nationale des Ponts et Chaussees, Paris, France. B.S. Eng. – 1987 Structural Engineering, University of Damascus, Syria. INDUSTRIAL EXPERIENCE:

2011-Present: Senior Structural Engineer, Martinrea, Troy, Michigan

• Responsible to provide CAE support to the fuel line business by conducting all the structural analysis requirements including the nozzle loading as well as the vibration fatigue on the gas and brake lines.

• Also supporting the chassis business by conducting stiffness, strength and durability analyses on engine cradles, and the different links of the suspension system.

• For new business, responsible for improving the initial design by reducing mass and increasing stiffness and durability of the product in order to increase the chance of winning the business.

• For awarded programs, provide the necessary CAE support during the different phases of the program to ensure the elimination of any fatigue cracks that might show during testing.

• Running on regular basis the FEA software: Hypermesh, nCode-DesignLife, Nastran, Abaqus, Optistruct, and Ls-Dyna.

• Represented Martinrea in the LightWeighting World Expo-2018 with a presentation about “ Light- Weighting Innovations for Chassis Subframes”

• Represented Martinrea in the Great Design in Steel Conference-2013 with a paper entitled “Pre-Form Solutions for Hydro-Forming Challenges”

2010- 2011: CAE Durability Engineer, Truck Durability Group, Chrysler Tech Center

• Conducted fatigue analysis using NASTRAN, ABAQUS, and nCode software for new Chrysler truck programs.

• Analysis covered the frame brackets and components like the control arm, and the track bar.

• Responsibility included also conducting optimization analysis of the rear-spring bracket using Optistruct, and clamping/slippage analysis of different frame brackets using Abaqus. 2008 – 2009: Senior Product Engineer, ArcelorMittal Tubular, Plymouth, Michigan.

• Responsible for designing and analyzing chassis and suspension systems that would be manufactured using ArcelorMittal tubes.

• Responsibility included working with the automotive customers to refine and optimize their original design and to propose solutions and suggestions that would lead to a lighter and more efficient design while still meeting the stiffness, and durability requirements. 2005 – 2008: CAE Specialist, Chrysler LLC, Die Engineering Group, Warren, Michigan

• Provided FEA expertise and solutions to the Die Standards Group.

• Main responsibility was to conduct FEA structural analysis (static and dynamic) to evaluate the strength of new stamping and trimming dies, and to investigate through FEA analysis the root causes of cracks and failure in working dies, and to propose effective solutions and remedies.

• Responsibilities included also conducting FEA optimization analysis to come up with innovative design ideas to reduce die weight and cost.

• As the only FEA analyst in my group, I had the responsibility to be independent but also to work closely with my cross-functional team members to support the issues they were facing in different plants. Also I had to prepare the reports of my FEA studies, and to present my findings to the upper management, to Corporate Safety, and to different plant managers.

2002 – 2004: CAE Manager, IntroTech, Inc., Troy, Michigan.

• Supervised a group of four CAE engineers conducting a verity of CAE consulting works

• Simulation projects included numerous pendulum/bar/barrier crashes testing of bumper system for the Ford Mustang that used Pullman hot formed technology for the beam

• Other programs included front and side impact simulation using Ls-Dyna, and the investigation of the use of structural foam as reinforcement for the B-pillar to reduce intrusion, also the use of hot formed cross member in the floor to meet impact requirements.

1996 – 2001: CAE Specialist, LTV Steel Company, Inc. Southfield, Michigan.

• Conducted numerous metal forming and hydro-forming simulations using Ls-Dyna in order to support the design and development of automotive components made from steel produced by LTV.

• Developed good understanding and familiarity with steel manufacturing process and sheet metal mechanical properties.

• Represented LTV in several Auto-Steel Partnership programs, and actively participated in the simulation activities of these programs.

• Worked with Ford Motor Company Engineers to develop a procedure to predict dent resistance of automotive panels

• Participated in the steel industry program Ultra-Light Steel Auto Body (ULSAB). Attended and presented LTV at the ULSAB final meeting in Yokohama, Japan. 1994 – 1996: CAE Analyst, Engineering Technology Associates, Inc. Troy, Michigan.

• Provided training and support for LS-Dyna for metal forming application.

• Conducted several metal forming simulation consulting jobs. TEACHING EXPERIENCE:

2000 – 2003: Instructor, Society of Automotive Engineers.

• Instructed the 3-day seminar “Fundamentals of Finite Element Linear Analysis in Solid/Structural Mechanics”.

1999 – 2004: Adjunct Faculty, University of Michigan-Dearborn, Lawrence Tech University, and Oakland University

• Developed and taught the courses “Finite Element Analysis”, “Structural dynamics” and “Numerical Methods in Engineering”
