Solutions for the point force and line load suddenly applied in a linear elastic fluid-infiltrated porous solid are rederived in a manner that emphasizes the relation to solutions for the homogeneous diffusion equation. Specifically, the stress, displacement, and pore pressure due to instantaneovs and continuous injection of fluid mass are obtained. These are differentiated to yield solutions f...

Strain in granular materials in quasistatic conditions under varying stress originate in (I) contact deformation and (II) rearrangements of the contact network. Depending on sample history and applied load, either mechanism might dominate. One may thus define rheological regimes I and II accordingly. Their properties are presented and illustrated here with discrete numerical simulation results ...

The paper reviews the method of complex potential functions developed by Green and Collins as applied to axisymmetric mixed boundary value problems in elasticity for the half-space. It is shown how the method can be applied to problems in several coupled potential functions such as adhesive and frictional contact problems, to problems involving annular regions and to problems in thermoelasticit...

Abstract Lung is the respiratory organ and important hematopoietic of human body, which easily damaged under impact load. Therefore, studying mechanical behavior lung load an way to understand its damage mechanism it. Compression experiments porcine tissue at a wide strain rate (0.001-3000 s −1 ) were carried out room temperature. The modifications made for highly accurate measurement due low w...

introduction: the aim of this study was to evaluate the effect of proximal contour of class ii composite restorations placed with straight or contoured matrix band using composite resins with different modulus of elasticity on stress distribution by finite element method. methods: in order to evaluate the stress distribution of class ii composite restorations using finite element method, upper ...

In this paper, vibration analysis of thick functionally graded beam with simply supported boundary condition under constant axial load is studied. The beam has a uniform cross-sectional area and the mechanical properties of the fungtionally graded beam are assumed to be vary through the thickness of the beam. Fundamental relations, the equilibrium and stability equations based on the displaceme...

The surface of dormant Bacillus anthracis spores consists of a multilayer of protein coats and a thick peptidoglycan layer that allow the cells to resist chemical and environmental insults. During germination, the spore coat is degraded, making the spore susceptible to chemical inactivation by antisporal agents as well as to mechanical inactivation by high-pressure or mechanical abrasion proces...

A plane static symmetric problem of theory elasticity for a piecewise homogeneous isotropic with an interface in the form sides angle, containing small-scale interfacial shear cracks at corner point and loaded internal semi-infinite crack, was considered. The exact solution to this constructed by Wiener-Hopf method combination apparatus Mellin integral transform. stress intensity factor tips de...
