M2 - Calculations and Simulations in Mechanical Engineering

This EU is applied to the "innovative mechanical engineering project." The aim is to give students the tools they need to simulate the creation of a business, based on the product or range of products developed in the innovative project.

This EU is divided into:

course taught by professionals from the world of entrepreneurship

consultations provided by professionals to support students (groups of up to three students) in simulating the creation of their own business.

This course provides a general introduction to 1) the physics and mechanics of granular media and 2) their modeling using discrete methods (DEM). The multiscale nature of granular materials is discussed from the microscopic scale (contact interactions) to the macroscopic scale (structure scale). A phenomenological description of macroscopic behavior and microscopic properties is discussed for the static, quasi-static, and flow states of granular media. Micro-mechanical models and scale-changing approaches based on dimensionless analyses, averaged quantities, force transmissions, and the existence of anisotropies are introduced. The influence of particle properties and contact interactions on microstructure is also discussed. Discrete approaches (Discrete Element Methods (DEM)), regular approaches (Molecular Dynamics) and non-regular approaches (Contact Dynamics) are presented. In particular, the Contact Dynamics method will be implemented on simple examples using the LMGC90 calculation code.

This teaching unit is common to both the CSIM and Biomechanics courses. It combines skills in the mechanics of rigid solids and imaging. It applies equally to issues in biomechanics, robotics, and many other fields related to motion analysis, such as motion capture for video games. It includes a theoretical component consisting of lectures and tutorials, and a practical component consisting of lab work carried out in conjunction with the UFR STAPS.

The aim of this course is to prepare students for job interviews by giving them the keys to promoting their past experiences.

This training is based on interview simulation games built on the basis of existing job offers.

Labor law here focuses on analyzing the main rules of the employment contract, in particular the obligations of the employee, the obligations of the employer, and the termination of the employment relationship.

Although natural composite materials have been used for thousands of years, advanced composite technology has only been used in the aerospace industry for the past fifty years. Applications are increasingly varied: from aircraft structures and hydrogen tanks to tennis rackets and boats. The objective of this course is to analyze and design structures made of laminated composite materials using industrial calculation codes. To do this, a presentation of the different components of petrochemical or natural composites is given. Next, the implementation processes are discussed. Finally, a theoretical and applied study of laminated composites is conducted. A practical application of these important theoretical concepts is carried out using industrial calculation software (ANSYS) during practical work and a project.

Field measurements are increasingly used in engineering, particularly in mechanics. The aim of this module is to present the basics of different imaging methods using image interpretation models of increasing complexity.

We begin by defining the operating principles of imaging devices, then we present some mathematical morphology tools in order to extract statistical information on quantities of a geometric nature.

We then discuss infrared thermography methods using two interpretation models: camera calibration and thermal problem inversion to identify heat sources.

Image correlation methods are finally presented, with an emphasis on the various underlying interpretation models (camera, transformation, optical flow conservation, likelihood criterion).The course ends with a comparison between experimental measurements and a digital model using a finite element model registration method. The theoretical courses are supported by practical sessions that allow students to apply the processing methods and illustrate the influence of the main analysis parameters.
