We describe a theory of blood hammer in a long and stiffened artery affected by the presence of plaque. Based on the model of a viscous fluid in laminar flow, we derive explicit expressions of oscillatory pressure and wall shear stress when part of the blood vessel is lined with thin ...
A theoretical model describing the progressive extensible plastic collapse of thin-wall conical and cylindrical shells is presented. The proposed theory enables the load-deflection curves during axial compression following the deformation history of the shell to be evaluated. The comparison of theoretical ...
Effect of reinforced stringers and rings wave propagation of the shell was analyzed and mechanism of vibration depression was discussed by wave propagation theory. It is demonstrated by the numerical results obtained from the frequency wave number spectrum procedure that the reinforcement scheme is quite...
athe maximum shear will depend on the sign of the principal stresses as well as their magnitude,and in two-dimensional stress system,such as that in the wall of a thinwalled pressure vessel,the maximum value of the shear stress may be given by putting .the maximum shear stress theory is ...
