Nikolai Weber, Dr.-Ing.
Managing Engineer

Düsseldorf (Germany)

Mr. Weber specializes in computational fracture mechanics, coupled fluid-solid interaction and fracture propagation, and hydraulic fracturing. His specific expertise includes numerical modeling of physical phenomena and technical systems, and the finite element analysis (FEA). Mr. Weber has a broad background in mechanical and computational engineering, simulation science, and numerical modeling.

Prior to joining Exponent, Mr. Weber was a research fellow at the RWTH Aachen University (Germany), where his research focused on numerical modeling of the hydraulic fracturing process. He modeled and implemented the coupled phenomena of fluid flow, solid deformation and crack propagation in rocks within the framework of the eXtended Finite Element Method (XFEM). Moreover, Mr. Weber verified the software tool on experiments that were conducted on a large-scale testing facility.

Within Exponent, Mr. Weber analyzed various industrial and mechanical structures and investigated the failure mechanisms among others for cranes, cooling towers, and high-temperature furnaces.
