Numerical methods such as boundary element and finite element methods are widely used for the stress analysis in solid mechanics. This study presents boundary element method based on the displacement discontinuity formulation to solve general problems of interaction between hydraulic fracturing and discontinuities. The crack tip element and a higher order boundary displacement collocation techn...

The fundamental questions arising in mechanics are: Why?, How?, and How much? The aim of this series is to provide lucid accounts written by authoritative researchers giving vision and insight in answering these questions on the subject of mechanics as it relates to solids. The scope of the series covers the entire spectrum of solid mechanics. Thus it includes the foundation of mechanics; varia...

Throughout John Wheeler's career, he wrestled with big issues like the fundamental length, the black hole and the unification of quantum mechanics and relativity. In this essay, I argue that solid state physics – historically the study of silicon, semiconductors and sand grains – can give surprisingly deep insights into the big questions of the world.

Experimental observations revealed that the stagnant zone, which forms in the lower central part of a blast furnace, is an important feature of solid flow, and that it is affected strongly by gas flow. However, it is difficult to model this feature within the framework of continuum mechanics without empirical or arbitrary treatments. This paper reports the use of discrete particle simulation fo...

Explosion dynamics is a broad field of applied research based on applying the principles of thermodynamics, chemical reaction kinetics, fluid and solid mechanics to studying accidental and deliberate explosions. Research in this field and related areas such as propulsion has been carried out at Caltech since 1993 in Joe Shepherd’s Explosion Dynamics Laboratory. Our research activities can be br...

Waste management is a complex and detailed process that involves evaluation of certain important factors, such as a geological, geotechnical, hydrological, hydrogeological, climate, urban management, environmental, along with social, cultural, and psychological parameters. Unfortunately, in Iran, there is minimal evaluation of initial parameters and in some cases even don’t exist. The purpose o...

Some new developments of conjugation-based sparse approximate inverse preconditioners are considered in application to problems of solid and structural mechanics. A block version of the AINV algorithm and its stabilized modification are presented. The stabilized AINV algorithm, which in exact arithmetic is breakdown-free for any SPD matrix, is found to result in robust preconditioners even in d...

Reduction theory for mechanical systems with symmetry has its roots in the classical works in mechanics of Euler, Jacobi, Lagrange, Hamilton, Routh, Poincaré, and others. The modern vision of mechanics includes, besides the traditional mechanics of particles and rigid bodies, field theories such as electromagnetism, fluid mechanics, plasma physics, solid mechanics as well as quantum mechanics, ...
