conference, Cenaero, in partnership with Onera and Cemef, organizes a
mini-symposium entitled “Damage to fracture strategies,
elasto-plastic crack initiation and propagation”. The
objective is to extend the knowledge on material non-linearities
aspects within the framework of fracture, embedding the activities of
the SIMUCOMP project.
The abstract must be submitted by December 15, 2011 at the latest.
The description of the mini-symposium is provided here under:
reduction of new industrial products implies weight and shape
optimization. For other products, such as large parts of existing
power plants, it can be relevant to extend the predefined lifespan. Both approaches require the improvement of the knowledge of the
phenomena that can occur during the lifetime of those products,
including the failure process, which is generally modeled using two
However, the bridge between those two parts of a same problem, which is the assessment of the total life of a part, is still difficult to realize. The transition between continuous damage growth and fracture initiation followed by propagation gives rise to both mechanical and numerical issues.
This mini-symposium tends to gather contributions on damage modeling, fracture mechanics (linear elastic, elasto-plastic), methods to combine both approaches, crack initiation and propagation (cohesive zone models, domain integrals, energetic approaches).
