Mechanical Engineering, Aviation & Aerospace - Multibody Dynamics, (Coupled) Loads Analysis, Accelerations, MBD, FEA, MBS, Mechanisms, Loads and Dynamics, Craig Bampton Modal Synthesis, ADAMS, Nastran, Automation, Python API

Subject matter expert in simulation of complex dynamic events such as accidents, crashes, impacts through rigid-body and flexible body dynamics. Applications include simple to complex mechanical systems analysis while interacting with aerodynamics loads and/or thermal effects. Maz's experience is in separation analyses, landing gears, launch mechanisms, release mechanisms, missiles, solar arrays, gear boxes, seat mechanisms, satellite deployment, complex contact mechanics in systems simulations, and more. Such simulations are verified and validated through the following approaches: (1) replying on lab test data from literature, (2) comparison against lab test data, (3) random seeding of inputs, running large scale Monte Carlo Analyses and validating that the individual sub-mechanism follow mechanical engineering principles.
