## IMI Workshop--CoMFoS15: Mathematical Analysis of Continuum Mechanics and Industrial Applications

Nov.16, 2015 - Nov. 18, 2015

**IMI Workshop--15th International Conference**

**CoMFoS15: Mathematical Analysis of Continuum Mechanics and Industrial Applications****http://www.imi.kyushu-u.ac.jp/eng/events/view/966**

**Keywords:**

Continuum mechanics, Fracture mechanics, Mathematical modeling, Industrial applications

**Aim and Scope:**

CoMFoS15 is a three-day international conference on mathematical aspects of continuum mechanics of solids with participants with diverse backgrounds from mathematics, physics, engineering, and industry. The conference consists of various kinds of lectures including special lectures by keynote speakers. We focus on mathematical theory and numerical simulations related to fracture mechanics, elasticity, plasticity, scattering, inverse problems, optimal shape design, etc. These problems play an important role in engineering and industry, and further development of mathematical understanding for them is needed to make possible future applications.

**Expected Outcome:**

Each lecture is followed by ample discussion time to provide space for an inspiring research debate among the participants on the above topics. We expect the discussion to focus in particular on finding new mathematical research directions in continuum mechanics based on the engineering viewpoint and industrial requirements, and investigating future engineering and industrial applications inspired by the theoretical results presented by mathematicians and theoretical engineers at the conference.

**History of CoMFoS and MACM:**

The conference series “CoMFoS” was started in 1995 and then had been organized by the Activity Group of JSIAM “Continuum Mechanics Focusing on Singularities (CoMFoS)” since 2005. The activity group was renamed “Mathematical Aspects of Continuum Mechanics (MACM)” in April 2010. It started as a research community of applied mathematicians and engineers working mainly on solid continuum mechanics and fracture mechanics. At present, it gathers not only mathematicians and engineers but also researchers in physics and industry who discuss mathematical aspects of continuum mechanics related to wider topics such as

fracture and damage mechanics,

elasticity and plasticity,

optimal shape design,

scattering and inverse problems,

visco-elastic materials,

particle methods,

free boundary problems, etc.
