A justification of the Timoshenko beam model through Γ-convergence
, 2017 We validate the Timoshenko beam model as an approximation of the linear-elasticity model of a three-dimensional beam-like body. Our validation is achieved within the framework of Γ-convergence theory, in two steps: firstly, we construct a suitable ...

A Study of the Fractal Bending Behavior of Timoshenko Beams Using a Fourth-Order Single Equation
BuildingsIn this paper a new generalized fractal equation for studying the behaviour of self-similar beams using the Timoshenko beam theory is introduced. This equation is established in fractal dimensions by applying the concept of fractal continuum calculus Fα ...

Timoshenko beam bending solutions in terms of Euler-Bernoulli solutions
, 1995 The Timoshenko beam theory is an extension of the Euler-Bernoulli beam theory to allow for the effect of transverse shear deformation. This more refined beam theory relaxes the normality assumption of plane sections that remain plane and normal to the ...
