creepmodeller

Creepmodeller is an open-source software tool designed for the analysis and simulation of creep behavior in materials, particularly metals and alloys subjected to high temperatures and sustained loads. Creep is a time-dependent deformation process that occurs when materials are exposed to stress over extended periods, often leading to structural failure. The software is widely used in industries such as aerospace, power generation, and nuclear engineering, where components operate under extreme conditions.

Developed primarily for researchers and engineers, Creepmodeller provides a platform to model and predict creep deformation using various constitutive models, including the Norton-Bailey, power-law, and time-hardening models. It integrates numerical methods such as finite element analysis (FEA) to simulate stress, strain, and damage evolution in complex geometries. The tool supports parametric studies, allowing users to evaluate the impact of different material properties, loading conditions, and environmental factors on creep behavior.

The software is built on a modular architecture, enabling users to customize material laws and boundary conditions. It also includes visualization tools for interpreting simulation results, such as strain maps, stress distributions, and failure progression over time. Creepmodeller is compatible with common file formats used in computational mechanics, facilitating integration with other simulation packages.

While primarily focused on creep analysis, Creepmodeller can also be extended for related phenomena like stress relaxation and fatigue. It is distributed under an open-source license, allowing for community contributions and modifications. The software is maintained by a team of developers and researchers, with documentation and user forums available for support. Its accessibility and flexibility make it a valuable resource for both academic and industrial applications in materials science and structural integrity assessments.
