About us

We are MATFEM, consulting engineers in the fields of materials science and finite-element simulation. Our interdisciplinary team is organized in three principal departments:

MATFEM Softmat FEM Services Commonlab

Softmat develops the material model MF GenYld + CrachFEM and provides auxilary utilities. Commonlab determines suitable simulation data for your materials in cooperation with partner laboratories. FEM Services carries out simulations and implements new modelling techniques.

A brief history

After receiving his doctoral degree on Material Science from the Technical University of Munich, Dr Helmut Gese founds the engineering consultancy MATFEM Ingenieur­büro Dr. H. Gese in May 1993. The company focuses on modelling mechanical and coupled thermal-mechanical problems with the Finite-Element Method (FEM) with strongly nonlinear material behaviour: sheet metal forming in automotive and aerospace applications and nonlinear contact problems in knee endprotheses.

Gernot Oberhofer joins the company in October 1993 as consultig engineer for FEM. He just finished his Diploma degree on material modelling for biomechnical applications.

In 1998 MATFEM starts a service to characterize material cards for nonlinear FEM. The required data is obtained from experiments at different partner labs. This will later be known as the CommonLab branch.

In 1998 Professor Harry Dell joins MATFEM. He brings in a strong expertise in modelling localized necking in sheet materials. In the same year MATFEM starts activity in crashworthiness simulation with focus on material models.

In January 1999 Helmut Gese and Gernot Oberhofer are partners in the newly-formed company MATFEM Partner­schafts­gesellschaft Dr. Gese & Oberhofer.

Prof. Dell’s program CrachLab is published in 2000. With the help of this software, forming limit diagrams can be calculeted based on the strain-hardening behaviour of a material.

From 1999 to 2000, Gernot Oberhofer and Harry Dell implement user material models for LS-DYNA®. The first model was a model for wrought magnesium developed in an industrial research project.

Later, models for polymers and porous polymers are developed in customer projects (2001–2004), alongside the characterization of the material cards in cooperation with partner labs.

In 2000–2001, CrachLab’s algorithm to predict localized necking is successfully applied to non-linear strain paths in successive stamping and crash processes in a common project with partners from industry. Helmut Gese coordinates this project for MATFEM.

MATFEM develops the failure model CrachFEM, which can be used in explicit-dynamic finite-element simulations. ESI implemented CrachFEM into the FEM codes PAM-Stamp and PAM-Crash. Validation results of a side crash from an industrial project are presented on EuroPAM 2003.

The paper of Hooputra et al. (2005) summarises validation work done at BMW on aluminium extrusions and makes MATFEM’s fracture models widely known.

In 2005 and 2006 Prof. Dell and Gernot Oberhofer extend the CrachFEM model to a full user material model by adding the modular elasto-plastic model MF GenYld. Later, the material model MF GenYld + CrachFEM is coupled to LS-Dyna and Radioss.

The NADIA research project (2006–2010)is financed by the European Commission and deals with modelling high pressure die-cast alloys. In that project, MATFEM develops a method of mapping of process parameters to the crashworthiness simulation in cooperation with MAGMA®.

In 2010, the 1st MATFEM Conference is held in Schloss Hohenkammer. The conference will be an established biennial meeting for materials and simulation specialists.

By 2015, MF GenYld + CrachFEM incorporates modules to model organic sheets with a woven lattice of glass fibers and other unidirectionsl composite materials.

In the following years MATFEM develops a very efficient solution for short-fibre reinforced thermoplastics: After mapping the principal fibre orientation and the degree of orientation from the mould-filling simulation, MF GenYld + CrachFEM can represent the local deformation and failure accurately.

A further development focus from 2018 to 2021 are orthotropic material models for metals and polymers produced by additive manufacturing.

The company changes its legal form to a public limited company (GmbH) in 2022 and celebrates its 30th birthday in 2023.
