The paper deals with classical problem for cracks dislocated in a certain very specific porous elastic material, described by a Cowin-Nunziato model. We propose a method based upon a reducing of stress concentration problem for cracks to some integral equations. By applying Fourier integral transforms the problem is reduced to some integral equations. For the plane-strain problem we operate wit...

As was seen in previous modules, stress analysis even of simple-appearing geometries can lead to complicated mathematical maneuvering. Actual articles | engine crankshafts, medical prostheses, tennis rackets, etc. | have boundary shapes that cannot easily be described mathematically, and even if they were it would be extremely difficult to fit solutions of the governing equations to them. One a...

DETERMINATION AND STUDYING OF STRESS DISTRIBUTION IN VARIOUS ANKLE-FOOT ORTHOSES: EXPERIMENTAL STRESS ANALYSIS

During last two decades, most of the named entity (NE) machine transliteration work in India has been carried out by using English as a source language and Indian languages as the target languages using grapheme model with statistical probability approaches and classification tools. It is evident that less amount of work has been carried out for Indian languages to English machine transliteration.

To determine flow curves of a material, whose plastic deformation is produced by martensitic transformation, transformation strains of a martensite plate must be characterized [1–3]. Most studies along this line adopt results obtained by the phenomenological crystallographic theory of martensitic transformation [4,5]. The theory is based on finite deformation analysis, which needs involved comp...

Firstly current status of temperature and thermal stress research of refractory product at home and aboard are analyzed. Finite element model of two classical refractory products is building by using APDL language. Distribution law of temperature and thermal stress of two typical refractory products-ladles and tundish are analyzed and their structures are optimized. Stress of optimal structure ...
