Numerical study of the Sturm–Liouville problem [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization
The article discusses the general Sturm–Liouville problem. To solve it numerically, a new algorithm is proposed, which is based on the varia-tional principle and does not use saturation.

The problem of dynamic cavitation in nonlinear elasticity [PDF]

open access: yes, 2012
The notion of singular limiting induced from continuum solutions (slic-solutions) is applied to the problem of cavitation in nonlinear elasticity, in order to re-assess an example of non-uniqueness of entropic weak solutions (with polyconvex energy)

ELASTIC GRAPHS [PDF]

open access: yesForum of Mathematics, Sigma, 2019
An elastic graph is a graph with an elasticity associated to each edge. It may be viewed as a network made out of ideal rubber bands. If the rubber bands are stretched on a target space there is an elastic energy. We characterize when a homotopy class of maps from one elastic graph to another is loosening, that is, decreases this elastic energy for all

Tissue elasticity and the ageing elastic fibre [PDF]

open access: yesAGE, 2009
The ability of elastic tissues to deform under physiological forces and to subsequently release stored energy to drive passive recoil is vital to the function of many dynamic tissues. Within vertebrates, elastic fibres allow arteries and lungs to expand and contract, thus controlling variations in blood pressure and returning the pulmonary system to a ...

Rotational Elasticity [PDF]

open access: yesThe Quarterly Journal of Mechanics and Applied Mathematics, 2011
We consider an infinite 3-dimensional elastic continuum whose material points experience no displacements, only rotations. This framework is a special case of the Cosserat theory of elasticity. Rotations of material points are described mathematically by attaching to each geometric point an orthonormal basis which gives a field of orthonormal bases ...

THE INFLUENCE OF OBLIQUE COLLISION OF THE GASKET OF A GAS REGULATOR ON SAFETY SHUTDOWN [PDF]

open access: yesFiabilitate şi Durabilitate, 2012
In this work the author presents a theoretical study on the conduct during the impact of the gasket at the intake of combustible gas, when the regulatory mechanism is controlled by a thermostat.

Four simplified gradient elasticity models for the simulation of dispersive wave propagation

open access: yes, 2008
Gradient elasticity theories can be used to simulate dispersive wave propagation as it occurs in heterogeneous materials. Compared to the second-order partial differential equations of classical elasticity, in its most general format gradient elasticity ...

Patterns and rules for sensitivity and elasticity in population projection matrices [PDF]

open access: yes, 2009
Sensitivity and elasticity analysis of population projection matrices (PPMs) are established tools in the analysis of structured populations, allowing comparison of the contributions made by different demographic rates to population growth.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
