Mr. Rau specializes in solid mechanics, mechanical testing, stress analysis, and material behavior. His primary expertise is applying mechanical engineering principals to evaluate functional performance and conduct failure analysis of materials, medical devices, and consumer products. He has extensive experience with evaluating and testing final form product assemblies and structural materials including metals, polymers, ceramics, and biological tissues in a variety of applications. Mr. Rau’s specific expertise includes the evaluation of biological tissues and the mechanical interaction of tissues with devices. Using his knowledge of solid mechanics and material behavior, Mr. Rau provides product consulting support for functional evaluations, failure analyses, as well as verification and validation services for products, computational models, and test methods.
Mr. Rau has extensive experience conducting and overseeing mechanical testing programs for materials, complex assemblies, and tissues. He is proficient in the operation of mechanical load frames and specializes in the design of custom fixturing to meet unique client needs. Mr. Rau has performed standard and non-standard material tests on metals, polymers, ceramics, as well as other engineering and biomaterials, including Nitinol, ultra-high molecular weight polyethylene (UHMWPE), and polyetheretherkeytone (PEEK).
Mr. Rau has a thorough knowledge of standards pertaining to the evaluation of medical devices and biomaterials. Mr. Rau has experience developing customized testing protocols to evaluate both the mechanical performance of medical devices and how those devices interact with human tissue and physiology. He has developed and implemented numerous methods for testing both hard and soft biological tissues. Mr. Rau has designed several customized protocols for testing ocular mechanics, soft tissue mechanics, as well as bone and joint mechanics in order to answer unique questions for clients.
Mr. Rau's analytical capabilities include linear and non-linear finite element analysis (FEA) and theoretical fracture mechanics. Mr. Rau's research interests include verification and validation ("V&V") for computational modeling of medical devices. He serves on the ASME Codes and Standards subcommittee: ASME V&V 40 Subcommittee on Verification and Validation in Computational Modeling of Medical Devices, and is currently active in developing guidance documents on V&V for computational modeling of medical devices.
