Location of courses: ENSEIRB-MATMECA Talence
Language: English
Distribution of courses: 24h of lectures
Description:
The long term durability of structures is an important challenge for engineers. Detection methods show that
many cracks may be present within a structure. Fracture mechanics allows deciding whether these cracks
can be tolerated without risk or whether it is necessary to repair the part. There are two main objectives of
the course: i) introduce the main concepts of rupture and fatigue used for damage tolerance design of
structures and ii) the basic for modeling and designing structures against fatigue crack initiation. Indeed the
damage tolerance methodology is used in aeronautics and some other industrial sectors but cannot be
always used. This is for instance the case in automotive industry for designing safe life structures.

loading, etc.)

• Formability
• Internal stress
• Contact mechanics
• Crystallographic textures
Specific learning outcomes of the course
At the end of this course, the student will be able to:
• Explain the fundamental assumptions underlying several continuum plasticity theories (J2
deformation theory, yield surface, normality rule, J2 flow theory, anisotropic extensions, etc) and single
crystal theory (e.g. Schmidt rule);
• Explain and identify the key technological and scientific issues in the most important forming
operations: rolling, deep drawing, extrusion, wire drawing, forging.
• Describe how metal forming operations are affected by a few important phenomena including:
plastic localization, damage, internal stresses, texture development, plastic anisotropy, contact and wear,
high temperature microstructure evolution;
• Calculate, analytically, the evolution of stress and strain in plastically deforming samples/crystals
under homogenous loading;
34
• Use a commercial finite element code to simulate forming operations based on existing input files
that can be modified to test different conditions/parameters;
• Critically assess/compare numerical results to analytical model and make links with technological
issues;
• Report (writing and oral) on a study based on finite element simulations of a forming operation

The contribution of this Teaching Unit to the development and command of the skills and learning
outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled
“Programmes/courses offering this Teaching Unit”.
Evaluation methods:
The students will be individually graded based on the objectives indicated above. More precisely, the
evaluation involves the grading of
• a project, by groups of 3 or 4 students, based on the use of the finite element code Abaqus to
simulate a forming process under different operating conditions. The forming operation will be orally
presented to the rest of the class, illustrated by the results of the finite element simulations. The oral
presentation will be supplemented by a written report. The grading will account also for daily work during
the semester.
• a set of imposed exercises the day of the written exam
• the answers to one or two theoretical questions selected within a list of about 10 questions of
synthesis provided by the teachers during the year.
Teaching methods
Ex-cathedra lectures are given to present the plasticity theories as well as the additional scientific aspects
essential in metal forming operations (plastic localization, damage, internal stress, texture, contact and
wear, high temperature microstructure evolution). 7 to 8 sessions are organized during which students can
solve exercises with the support of an assistant. The rest of the time is devoted to the project which starts
with a presentation of the use of the finite element code. Each group is helped by a dedicated assistant.
The students can use Abaqus teaching licences to run simulations and analyze the results, with access to a
computer room.
