Missions

The engineer's primary duties are to:
1. Produce experimental results on means of characterization of thermomechanical properties at small scales (meso (bending of meso beams, image correlation), micro (micro-traction, micro-pillars, bending of micro beams, image correlation), nano (nanoindentation)) ;
2. Participate in the development and improvement of products and systems such as fixtures, test and measurement benches;
3. To lead and organize the development activity in relation with PhD students, engineers and teacher-researchers and technical staff.

Activities

1. Produce experimental results on means of characterizing thermomechanical properties at small scales on titanium alloys (meso, micro, nano):
a. Define the experimental protocols adapted to the needs of the research work and the capacities of the characterization equipment;
b. Carry out characterization campaigns
i. Micromechanical tests at room temperature and hot
ii. Multi-scale image correlation (in-situ and ex-situ)
c. Write test reports;
d. Contribute to the analysis of experimental results.
2. Participate in the development and improvement of products and systems such as fixtures, test and measurement benches:
a. Collect the development needs of the ICA-Albi staff (research projects, technical platforms, technological platform);
b. Participate in the reflection on the necessary technological needs and the development budget;
c. Participate in the commissioning of the benches.
3. Lead and organize the development activity in relation with PhD students, engineers and teacher-researchers and members of the technical pole:
a. Evaluate the technical feasibility of projects and the capacity to internalize product development in consultation with the technical pole personnel;
b. Create a network and coordinate the relationship with the suppliers and subcontractors solicited for the development (partnerships);
c. Capitalize on project data (plans, specifications, etc.).

Work Context

The Institut Clément Ader (ICA, CNRS UMR 5312) is a research laboratory dedicated to the study of mechanical structures, systems and processes. Our sectors of activity fall within those of the mechanical industries, with particular attention paid to projects in the fields of aeronautics, space, transport and energy. Our work generally focuses on modelling the mechanical behaviour of materials, its instrumentation and the study of the durability of the structures or products considered.

The ICA has about 80 research professors, 20 temporary researchers, 20 administrative staff, 90 doctoral students, as well as many interns. With the particularity of having :
- at the level of the supervisory bodies, staff belonging to four major institutions: UPS and INSA from the Ministry of Higher Education and Research, ISAE from the Ministry of Defence, Mines Albi from the Ministry of Industry;
- geographically, the staff is spread over four cities in the Midi-Pyrénées/Occitanie region: Albi, Figeac, Tarbes and Toulouse.
The management is composed of a director and two deputy directors, the three supervisory ministries being represented in this trio. The technical support team (BIATSS staff) is organised into three components, one for each ministry.

The laboratory is organised into four research groups:
- MSC group: Composite Materials and Structures ;
- SUMO Group: Surface, Machining, Materials and Tools;
- MS2M Group: Modelling of Mechanical Systems and Microsystems;
- MICS Group: Metrology, Identification, Control and Monitoring.

This research work is in line with the research themes of the MICS, SUMO and MS2M groups, for the understanding and metrological development associated with surface reactivity phenomena assisted by mechanical deformation.

The skills required of the engineer are centered on the understanding of the physical and chemical mechanisms responsible for the thermomechanical behavior of materials, particularly at small scales and subject to complex environments (oxidizing environment, extreme thermal environments, etc.). The studies around the micromechanical theme require the definition, design and development of characterization techniques towards small scales. The high temperature nanoindenters acquired in the framework of the ERC project HT-S4DefOx illustrate this evolution and the new skills to be acquired by the laboratory. Moreover, the design engineer will participate to the activities on the measurement of kinematic fields at small scales at high temperatures. The main mission of the incumbent will be to accompany this evolution of the ICA's research activities by contributing to the production of experimental results related to the characterization of the thermo-mechanical behavior at small scales in oxidizing environments on titanium alloys.
