THE ANALYSIS OF LIMIT INNER PRESSURE OF THICK WALLED TUBE AND SPHERE SHELL WITH DIFFERENT STRENGTH IN TENSION AND COMPRESSION BY THEORY OF GENERALIZED TWIN SHEAR STRESS STRENGTH
In this paper elastoplastic stress analyses for thick-walled tube and sphere shell with different strength in tension and compression are conducted using the theory of generalized twin shear stress strength. They include elastic limiting inner pressure,plastic limiting inner pressure,elastoplastic stress,and the relation between inner pressure and elastoplastic zoned radius of thick-walled tube and sphere shell. These results are dependent on tension-compression ratio of the material.
The experiment of the long distance diffraction propagation of detonation waves in a spherical shell of plastic bonded HMX/TATB=87/7 explosive has been conducted.
The radial symmetric motion problem was examined for a spherical shell composed of a class of imperfect incompressible hyper_elastic materials, in which the materials may be viewed as the homogeneous incompressible isotropic neo_Hookean material with radial perturbations.
The mathematical model of the mechanical system under consideration is presented in the form of a spherical shell, which is wetted by a spherical layer of liquid enveloping a rigid spherical core.
The specimens are made of a disperse ferromagnetic mixture with the magnetic susceptibility χc ≥ 1 400 SI units encased in a spherical shell made of a dielectric with the magnetic susceptibility χmd ? 1.
