Structural Engineering

The prediction of displacements in structures and solid bodies, the assessment of stresses and deformations located in different materials, the description of the non-linear mechanical behaviour are all fundamental tasks in design and optimization processes.

M3E offers services in the field of Structural Engineering and Solid Mechanics, in particular developing Finite Element Models of structural components and continuum bodies, adopting both best-in class commercial software solutions (ANSYS, ABAQUS, Straus7, etc.) and in-house developed codes.
In particular, M3E develops and maintains the M3E_GS library, a High Performance Computing finite element library for the solution of non-linear structural problems with 3D elements. Thanks to the specific competences of the staff, M3E is able to develop customized routines, that can implement specific constitutive laws according to the Clients’ needs (e.g. non-linear elastic, elasto-plastic, visco-plastic, etc.), particularly important when dealing with new materials. Moreover, M3E is able to endowed the FE codes with additional equations accounting for multi-physics problems and special type of finite elements.

The M3E’s team is able to build complex 3D model up to millions of elements, using best-in-class library (e.g. TetGen) to reproduce challenging geometry. Moreover, M3E is able to developed ad-hoc preprocessor and postprocessor, that allows to save an incredible amount of time and money in preparing the model and in extracting information from the results.

Main activities include:

  • the analysis of stresses and deformations in structures and continuous bodies
  • the non-linear material and geometry analysis of complex systems
  • the development and implementation of specific constitutive laws ( e.g. non-linear elastic, elasto-plastic, visco-plastic, etc.)
  • the 3D modelling of complex geometries, using structured and unstructured meshes, up to millions of elements

 

Main developed tools:

  • M3E_GS: High Performance Computing finite element library for the solution of non-linear structural problems with 3D elements.
