Comportamento termoelástico transiente no acoplamento de cilindros circulares concêntricos
… cylinders are homogeneous, isotropic and follow Hooke's law for elastic materials. Strain-temperature coupling is disregarded and the analysis assumes quasi-static behavior.

Análise de estruturas no estado plano de tensões e deformações com materiais elásticos, ortótropos e não lineares
… than the usual assumption of a generalized Hooke's law. The finite element method is used for solving plane stress and plane strain problems. This method leads to a system of non-linear equations, which requires an incremental-iterative procedure to achieve the solution. The theory is …

TRUSS ANALYSIS USING SINGULAR IMBEDDING METHOD
… conditions, compatibility relationships, and Hooke's law of material.</p><p>The final structural stiffness matrix equations are constructed for the different types of constraints. The unknown member areas are determined from the final structural stiffness matrix equations. The analysis …

Cord-Reinforced Cylindrical Shells
… The matrix is modeled using the generalized Hooke's law for an isotropic linear-elastic material. The theory that is used to model the cords was developed by Costello and includes the extension-twist coupling of the cords. For the shell, a set of differential equations for the displacements …

The mechanical testing of single nanofiber
… was measured with the help of AFM by satisfying Hooke's Law. The elastic properties of PLLA nanofiber were investigated with the atomic force microscope (AFM). The elasticity was calculated by analyzing the recorded force curves with the help of the Hertz model. Mechanical testing confirmed that …

An investigation of the effects of cold working upon copper
… For stresses below the elastic limit, Hooke's law and Poisson's ratio are applicable, but above the elastic limit relation to stress to strain follows a different law. Copper and steel are both ductile materials, and it is, therefore, logical to assume that they will show similarity of …

Método dos elementos finitos aplicado ao problema de escavação
… and non-linear material, although following Hooke's law for small increments of stresses. The mechanical parameters of the soil are function of the state of stresses. A finite element program was developped which can simulate the several phases of an excavation using the linear strain …

On the theory of the optical stretcher : optics, mechanics, and thermal effects
… The stresses inside the object are deduced from Hooke's law of elasticity. To take the particle's thermal expansion into account, a particular solution for the presence of a temperature gradient is derived. The temperature profile in the OS was determined experimentally using fluorescence ratio …

Modeling the Transient Effects during the Hot-Pressing of Wood-Based Composites
… due to the cellular structure of the mat. Hooke's Law was modified with a nonlinear strain function to account for the behavior of the flake mat in transverse compression. This part of the model gives insight into the vertical density profile formation through the thickness of the mat. …
