Associated Abaqus & UMAT Services
Beyond this specialised offering, we provide full-scale Abaqus consulting services and the related Consultant service package. Our advanced UMAT development expertise is complemented by the structured UMAT Consultant package, together with freelance simulation collaboration and its project package. We also support clients through Abaqus technical help and the dedicated Help & Support package, alongside focused UMAT problem-solving services and the corresponding UMAT Help package. For research collaborations, our UMAT freelancer services and UMAT Freelancer package ensure reliable model implementation.
All developments are aligned with research published in the International Journal of Plasticity and maintain compatibility with Abaqus/Standard, developed by Dassault Systèmes [1, 2, 3, 4]. Practical case studies and structured training are available through our Hydrogen modelling tutorial, Phase Field fracture tutorial, and other advanced tutorial packages.
Frequently Asked Questions – Abaqus UMAT Consultant
What is UMAT in Abaqus?
UMAT is a user material subroutine that allows implementation of custom material models not available in standard Abaqus.
Can you develop custom UMAT based on research papers?
Yes, we implement material models directly from scientific publications and validate them.
Do you provide source code?
Yes, full UMAT source code with documentation and tutorials is provided.
