This quantity offers a set of contributions on complex methods of continuum mechanics, that have been written to rejoice the sixtieth birthday of Prof. Holm Altenbach. The contributions are on issues regarding the theoretical foundations for the research of rods, shells and third-dimensional solids, formula of constitutive types for complex fabrics, in addition to improvement of recent ways to the modeling of wear and tear and fractures.

Advanced Methods of Continuum Mechanics for Materials and Structures

This quantity offers a set of contributions on complex methods of continuum mechanics, that have been written to have fun the sixtieth birthday of Prof. Holm Altenbach. The contributions are on issues on the topic of the theoretical foundations for the research of rods, shells and three-d solids, formula of constitutive versions for complicated fabrics, in addition to improvement of recent ways to the modeling of wear and tear and fractures.

The localisation of (8) provides the two equations (cf. Eqs. (34) and (35) in p. jK in V0 , (10) at ∂V0 . (11) Here, as emphasized by the Cosserats (top of p. jK represents a force in the direction of the actual axis noted i, but per unit area in the undeformed configuration. Equations (10)–(11) were given by Marcel Brillouin (1884, 1885). K =0, (12) one can revert to the actual (Eulerian form of the) equation of equilibrium as proved by Boussinesq (1869) since with (9) and (10) one has ∂ ∂X K But (see p.

Maxwell 1853). Eugène Cosserat defended his Sorbonne thesis in mathematics before a committee formed by Gaston Darboux (1842–1917), Paul Appell (1855–1930) and Gabriel Koenigs (1858–1931)—see Lebon (1910). This thesis on geometry was published in the Annales of the Faculty of Sciences of Toulouse in 1885. Darboux was the author of a formidable work—in four volumes— on the theory of surfaces and an ardent propagandist of the notion of mobile triad that was readily adopted by the Cosserats. A. Maugin an influential encyclopaedic treatise on rational mechanics (starting in 1893 with many augmented editions) and practically became the godfather of all mechanicians in France in the period of interest.

At this point it is appropriate to introduce the notion “frame of reference” formally. Imagine in a point O three rigidly connected, perpendicular pointers (“arrows”), e1 , e2 , and e3 . ” Definition 1 The body of reference is defined by a frame to which a set of points (in space) have been added, whereby a rigid body motion of all the points together with the frame is allowed. The position of the points are labeled relatively to the frame by establishing the reference coordinate system x1 , x2 , x3 with origin O: r ∗ = x 1 e1 + x 2 e2 + x 3 e3 , −∞ < (x1 , x2 , x3 ) < +∞.
