Ph.D. position available in France/Belgium: Optimization methods supported by multi-fidelity full-field meta-models and enrichment strategies dedicated to turbine engine design

Safran Aircraft Engines is a world-class engine manufacturer in the aerospace propulsion market - civil and military - and space. At CFM International, Safran Aircraft Engines develops and produces the CFM56 "bestseller", the most reliable engine of its generation in the single-aisle aircraft category. LEAP, its successor, was designed to equip new generations of single-aisle aircraft.

Simulation-based numerical optimization of arc welding process for reduced distortion in welded structures

This paper presents an effective numerical approach for welding process
parameter optimization to minimize weld-induced distortion in
structures. A numerical optimization framework based on coupled Genetic
Algorithm (GA) and Finite Element Analysis (FEA) is developed and
implemented for a low and a high fidelity model. Classical weakly
coupled thermo-mechanical analysis with thermo-elasto-plastic
assumptions is carried out for distortion prediction of numerical
models. The search for optimum process parameters is executed by direct
integration of numerical models and GA-based optimization technique. The
developed framework automatically inserts the process parameters into
the simulation models, executes the FE-based welding simulations and

Abaqus 6.13 - Live Webinar July 23

Abaqus 6.13 - Live Webinar! July 23, 9am EDT and 12 pm EDT. The latest release, Abaqus 6.13 delivers a number of powerful, customer-requested enhancements for modeling, meshing, visualization, contact, mechanics, and performance. These improvements enable customers to reduce development time and costs, while increasing the efficiency of the product development process through highly accurate simulations of real-world product and material behavior.

Finite element software with analytical sensitivity analysis

 

 As structural optimization can be, of course, greatly sped up with the use of analytical sensitivies (analytical gradients) of the e.g. stress with respect to geometrical design variables, I wanted to inquire which FE software has the functionality.  The ones I am aware of: NASTRAN can and ANSYS cannot. How about others?

 Many thanks in advance!

The use of IOSO Optimization and ABAQUS at Civil Structures of NPP (from ABAQUS Users' Conference)

At the stage of NPP civil structure design for determination of stress-strain state (SSS) at static and dynamic loading ABAQUS is widely used. Hereto the floor response spectra are determined for calculation of loadings on the equipment at special dynamic impacts (seismic, air shock wave, aircraft crash). In case if the obtained characteristics of SSS or spectral accelerations exceed maximum permissible values, designers take actions on strengthening the corresponding structural components.

Post-doct position : Isogeometry-based analysis and design

INRIA (the French national institute for research in computer science and control) has currently eight centres, and the Opale Project-Team is primarily located in the Sophia Antipolis Centre, near the city of Antibes. Our research focuses on functional and numerical analysis, and numerical simulation, with a special emphasis on optimization in science and engineering (compressible aerodynamics, electromagnetics, structural design, etc) with strong links with industry.
