Stress analysis in strain hardening two-layer composite tubes subject to cyclic loading of internal pressure

This section presents the formulation for optimum design of laminated composite tubes subjected to axisymmetric loads (internal and/or external pressure, axial force, torsional

Sources that can lead to deterioration of steam superheater tubes of a high pressure boiler were studied by a stress analysis, focused on internal pressure and temperature

Experimental results indicate that the stress-strain curve and the work hardening coefficient (n) of steel drawn in two passes and submitted to cyclic torsion are similar to

Ryan and McQueen observed that the presence of a stress peak in a constant strain rate flow curve leads to an inflection in the stress dependence of the strain hardening rate,

The irst part of the low stress curves, shown in Figure 1, indicted high levels of strain hardening coeicient ( h ) at low temperatures and high strain rates, determined

4, despite the non-Fourier heat conduc- tion analysis, temperatures of internal tubes of 13-layer MWCNT do not increase as expected and the temperature of each layer is less than

Multi-layer speckle tracking analysis showed significant reduction of circumferential strain of subendocardial layer, transmural CS gradient and longitudinal strain of all
