Nikolai Weber, Dr.-Ing.

Managing Engineer
Industrial Structures
Düsseldorf (Germany)

Dr. Weber specializes in computational engineering with a broad background in mechanical and structural engineering, simulation science, numerical modeling, and hydraulic fracturing. His specific expertise includes fluid induced cracking mechanisms and the coupled thermomechanical analysis of high-temperature systems. Dr. Weber has an extensive knowledge of finite element (FE) based software tools including nonlinear and dynamic behavior.

Dr. Weber supports clients in failure analysis and testing across a wide range of industries, including consumer products, electronics, energy, telecommunication, construction and automotive. He uses advanced knowledge of computational and image data analysis techniques such as volumetric data analysis to help improving his client’s products and performance. Moreover, Dr. Weber manages teams and oversees the operations of individual projects around the globe. He provides hands-on leadership for numerous business areas such as consumer products and medical devices.

Prior to joining Exponent, Dr. Weber was a research fellow at the RWTH Aachen University (Germany), where his research focused on numerical modeling and software development of hydraulic fracturing processes. He modeled and implemented the coupled phenomena of fluid flow, solid deformation and crack propagation within the framework of the Extended Finite Element Method (XFEM). Dr. Weber verified his software tool with fracking experiments on a large-scale testing facility.
