Welcome to Multi-FEAST© (Multi-axial FatiguE ASsessment Tool), the on-line resource for researchers and professional engineers working on uniaxial and multiaxial fatigue.

We are delighted to launch Multi-FEAST© after many years of scientific research and development.

Please take a look around: we hope you enjoy becoming part of our community!

The Multi-FEAST project


Our vision: accelerating the transfer of knowledge from academia to engineering practice by nurturing a vibrant community of industrialists, researchers, and students.

Our challenge: condensing the state-of-the-art knowledge of uniaxial and multiaxial fatigue into a FEM-independent post-processor.

Our success: Multi-FEAST© is an easy to use package allowing practitioners, researchers, and students to apply the most advanced findings in the uniaxial and multiaxial fatigue fields using a simple, efficient, sophisticated, and cost-effective software tool.

Our philosophy: the licencing arrangements for Multi-FEAST© are intended to cover the costs of maintaining the website, nurture the growing community of users and encouraging its educational use. We are happy to discuss multiple user licences, collaborative research, and teaching support with interested parties.

What Multi-FEAST does…

The Multi-FEAST© software has been developed to predict both the high-cycle fatigue strength and the fatigue lifetime of metallic structural components and welded joints. Multi-FEAST© can deal with constant and variable amplitude loading under uniaxial and multiaxial conditions. Both the high-cycle fatigue strength and lifetime are estimated following the Modified Wöhler Curve Method.

When performing fatigue assessments of notched components, you can use either nominal or local stress quantities. In the latter case, since the Modified Wöhler Curve Method is used in conjunction with the Theory of Critical Distances, Multi-FEAST© is designed to post-process the outputs directly from commercial finite element software packages. You can also use load histories gathered experimentally using standard transducers and strain gages as input files.

Finally, Multi-FEAST© also allows the Modified Wöhler Curve Method to be used to estimate fatigue damage in steel and aluminium welded structures subjected to constant or variable amplitude load histories, under uniaxial and multiaxial conditions. The assessment can be undertaken using nominal or hot-spot stresses, and also by using local quantities in terms of the Theory of Critical Distances or the Reference Radius Concept.
