The evaluation of tangential stress fields in linearly elastic orthotropic Saint-Venant beams under torsion is based on the solution of Neumann and Dirichlet boundary value problems for the cross-sectional warping and for Prandtl stress function, res

The virtual power principle (VPP) of continuum mechanics states a celebrated variational equality between external and internal virtual powers for any virtual velocity field conforming with linear kinematic constraints. The topic is here addressed to

In Continuum Mechanics a widely cited formula, due to Nanson (Mess Math 7:182–185, 1878), contributes the relation between the product of area and unit normal vectors relevant to corresponding surfaces in two configurations of a 3D body. A geometri

Nonlocal elasticity models are tackled with a general formulation in terms of source and target fields belonging to dual Hilbert spaces. The analysis is declaredly focused on small movements, so that a geometrically linearised approximation is assume

Functionally graded elastic annular nano-beams subjected to torsion are studied by a coordinate-free approach. Strain- and stress-driven integral elasticity models are formulated for investigation of structural behavior of beam-like components of nan

The general role of control windows is investigated by an assessment of the fundamentals of continuum dynamics in the spacetime context. The momentum rate of change of a continuous body is evaluated with reference to a control window travelling in th

There are, in each branch of science, statements which, expressed in ambiguous or even incorrect but seemingly friendly manner, were repeated for a long time and eventually became diffusely accepted. Objectivity of physical fields and of their time r

Nonlocal elasticity is addressed in the context of geometrically linearised structural models with linear and symmetric constitutive relations between dual fields, with physical interpretation of stress and elastic strain. The theory applies equally

The dynamical interaction between solids and fluids is a subject of paramount importance in Mechanics with a wide range of applications to engineering problems. It is, however, still a challenging topic of theoretical investigation. With a view to ca

The kinematics of generalized continua is investigated and key points concerning the definition of overall tangent strain measure are put into evidence. It is shown that classical measures adopted in the literature for micromorphic continua do not ob
