Advanced Constitutive Modeling, Nonlinear FEA & Computational Mechanics Consulting

I provide specialized R&D consulting services in computational solid mechanics, advanced constitutive modeling, material characterization, and nonlinear finite element analysis (FEA), helping industrial research teams develop predictive models and address complex engineering challenges.

I hold a Ph.D. in Mechanical Engineering and have over 12 years of experience in computational and experimental mechanics, including serving as a DFG-funded Principal Investigator in Germany.

Core Services and Expertise

1. Constitutive Modeling and Material Behavior

• Development, calibration, and implementation of nonlinear constitutive models for metals, polymers, rubbers, and composites.
• Modeling of nonlinear elasticity, plasticity, viscoelasticity, viscoplasticity, strain-rate-dependent behavior, and large deformation.
• Material parameter identification and model validation using experimental data.

2. Advanced Finite Element Simulation

• Nonlinear static and dynamic simulations using Abaqus/Standard and Abaqus/Explicit.
• Development and implementation of custom material formulations using UMAT, VUMAT, and UEL subroutines in Fortran.
• Structural, thermo-mechanical, and high-strain-rate analyses.

3. Multiscale and Microstructure-Based Modeling

• Crystal plasticity and microstructure-informed constitutive modeling.
• Size-dependent material behavior and multiscale computational methods.
• Investigation of deformation and hardening mechanisms in engineering materials.

4. Experimental Characterization and Validation

• Integration of experimental measurements with numerical simulations.
• Material model calibration and validation using mechanical testing data, including high-strain-rate experiments.
• Simulation-based evaluation of material and structural performance.

5. Simulation Automation and Engineering Analysis

• Parametric studies, Design of Experiments (DOE), and simulation workflow automation.
• Python, MATLAB, and Fortran programming for numerical modeling, data analysis, and post-processing.
• Fatigue and durability assessments using Abaqus and fe-safe.

Project Deliverables

Depending on the project scope, deliverables may include:

• Constitutive model formulations and calibrated material parameters.
• Custom Abaqus UMAT, VUMAT, or UEL subroutines.
• Validated finite element models and simulation results.
• Technical reports, documentation, and engineering recommendations.

Collaboration Opportunities

I am available for independent technical consulting, industrial R&D collaborations, and research partnerships. Projects can be conducted remotely or through mutually agreed arrangements, with scope, milestones, and timelines defined according to project requirements.

I welcome inquiries from materials technology companies, automotive and aerospace organizations, advanced manufacturing teams, and research institutions seeking specialized expertise in nonlinear material behavior and computational mechanics.
