ALLPLAN CAO 3D Software :

It allows the construction in 3D from field survey MNT and module GC voluminous. It thus becomes an essential assistant of the 3D modeling Finite elements providing the contours of the project.

ALGOR 3D modelling software :

Simulation Mechanical is a general calculation code using the Finite Element Method. Simulation Mechanical is designed for the treatment of all types of problems encountered by the disciplines of industrial mechanics and adapts particularly well for calculations of voluminal structures.

  Avène dam: Conditions of movement at the boundaries of nodes
  Avene dam: stress state under stress - detection of traction zone (potential cracking)

Below 3D modeling by BRL of a complex structure: the dam of the Couesnon - Mont Saint-Michel

3D modelling of the Couesnon Dam: Civil engineering - Foundation and ground   
    Results of a calculation: Deformation fields

This example demonstrates our ability to model complicated structures both in terms of the Civil Engineering structure and the Foundation-Structure and Mechanical Effort-Structure interactions.

Plaxis :

PLAXIS is a non-linear non-standard elastoplasticity analysis tool (5 parameters) with pore pressure considerations. PLAXIS is designed for 2D problems, plane deformation, or plane stresses. The elasto-plastic model allows calculations of displacements, stress conditions, limit loads and the evaluation of safety coefficients with respect to stability. PLAXIS allows the simulation of construction and excavation operations, which leads to a realistic evaluation of constraints and displacements.
