Solid mobile fabrics (foams, lattice fabrics, honeycombs, etc.) are beautiful and feature led to the production of an lively topic for structural, mechanical and fabric scientists in recent times. certainly, consistent development within the production thoughts are enhancing their homes and decreasing their charges; and mass productions and commercial purposes are starting. a massive mechanical challenge is the best way to represent and version the mechanical behaviour of those fabrics, that's useful for commercial layout and numerical predictions interested in a variety of purposes equivalent to mild weight constructions, strength absorbers.

This quantity comprises twenty-two contributions written through individual invited audio system from all a part of the area to the iutam symposium on mechanical houses of mobile fabrics. It presents a survey on contemporary advances within the characterisation and modeling of the mechanical houses of good mobile fabrics below static and dynamic loading in addition to their purposes in light-weight buildings research and layout. This quantity might be of curiosity to structural, mechanical and fabric scientists and engineers engaged on diversified elements of this new type of fabrics (for instance in microstructure remark, micromechanical and multiscale modeling, phenomenological types, structural impression behaviour and numerical validation).

This can be the main finished survey of the mathematical lifetime of the mythical Paul Erd? s, probably the most flexible and prolific mathematicians of our time. For the 1st time, all of the major components of Erd? s' study are coated in one venture. as a result of overwhelming reaction from the mathematical neighborhood, the venture now occupies over 900 pages, prepared into volumes.

This is followed by the prediction of the effective elastic constants and coefficients of thermal expansion of nanoporous materials with spherical or cylindrical voids. It is shown that the elastic constants of nanoporous materials can be tailored to desired values through pore surface modification or coating. Keywords Generalized Young-Laplace equation · Surface stress · Nanoporous materials · Effective elastic constants · Effective coefficient of thermal expansion 1 Introduction Surface forces have a substantial effect on the physical properties of materials at the nanoscale, as evidenced for example by the dramatic increase in the elastic constants of nanowires, nanobeams, nanoplates, etc.

Caty, A. King, and J. Adrien Abstract This paper summarizes different results obtained by the authors applying X-ray tomography to the study of cellular materials (metals, ceramics and polymers). From the 3D images, three different kinds of analysis are carried out. The first is image processing to retrieve the morphological characteristics (density, size, tortuosity) of the studied materials. The second is the analysis of the deformation modes using in situ or ex situ mechanical tests (tension, compression, fatigue).
