Enhanced Effective Thickness (EET) of curved laminated glass
Annals of Solid and Structural Mechanics - Tập 7 - Trang 71-92 - 2015
Approximate methods for calculating laminated glass (LG), a composite where thin polymeric layers are sandwiched by glass plies, are very useful in the design practice. The most common approach relies upon the definition of the effective thickness, i.e., the thickness of a glass monolith that, under the same boundary and load conditions, presents the same maximal stress or deflection of the lamina......
Bending and free vibration of functionally graded piezoelectric microbeams based on the modified couple stress theory
Annals of Solid and Structural Mechanics - Tập 10 - Trang 1-16 - 2017
A size-dependent model for bending and free vibration of functionally graded piezoelectric (FGP) microbeam is developed by using modified couple stress theory and a unified higher order beam theory. This model can be specialized to various beam models, such as Euler–Bernoulli, Timoshenko as well as Reddy beam ones and vice versa. The governing equations of motion and associated boundary conditions......
Inferring material parameters from imprecise experiments on soft materials by virtual fields method
Annals of Solid and Structural Mechanics - Tập 12 - Trang 59-72 - 2020
Inferring material parameters of soft materials, especially soft tissues from experiments, has always been a challenge because of the inaccuracy of specimen geometry, difficulty in proper gripping and difficulty in obtaining reliable displacement data. If one is able to obtain full field data with Digital Image Correlation or other similar techniques, we show that in spite of poor quality experime......
On causality of wave motion in nonlocal theories of elasticity: a Kramers–Kronig relations study
Annals of Solid and Structural Mechanics - Tập 12 - Trang 165-187 - 2020
In this paper, the subject of the principle of causality and the physical realizability in the wave motion characteristics within a linear nonlocal elastic medium is examined. The principle of primitive causality is examined via Kramers–Kronig (K–K) relations and the principle of relativistic causality or the Einstein causality is examined via wave motion responses. Gradient as well as integral ty......

Smooth/non-smooth contact modeling of human crowds movement: numerical aspects and application to emergency evacuations
Annals of Solid and Structural Mechanics - Tập 2 - Trang 69-85 - 2011
The aim of this paper is to develop on discrete models that reproduce the behavior of a crowd of people in several emergency evacuation situations. The first step in this study is to determine how to treat contacts between pedestrians. For that, three already existing discrete approaches, one smooth and two non-smooth, originally proposed to simulate the collisions of granular assemblies, are firs......
Magneto-thermo-mechanical modeling of a Magnetic Shape Memory Alloy Ni-Mn-Ga single crystal

On standard dissipative gradient models
Annals of Solid and Structural Mechanics - - 2010
A general presentation on gradient models for solids in thermo-mechanics is given in this paper. Firstly, it is shown that the introduction of the gradients of the internal variables can be conveniently done under the formalism of the generalized standard materials. The derivation of the governing equations and the associated boundary conditions of a solid can be derived in a straightforward manne......
Numerical study of a thermo-hydro-mechanical damage model for unsaturated porous media

Elastic–plastic analysis of rotating disks having non-linearly variable thickness: residual stresses by overspeeding and service stress state reduction
Annals of Solid and Structural Mechanics - Tập 1 - Trang 87-102 - 2010
Two models for evaluation of elastic and elastic–plastic stress and strain in non-linear variable thickness rotating disks, either solid or annular, subjected to such a rotational speed to determine stresses beyond yielding are presented. The first model regards the elastic field and the second concerns the elastic–plastic field, assuming that material hardening is isotropic and follows a most gen......
