Compression Behavior of Pa-12 Pipes Under Large Displacements: Crimson Publishers

Compression Behavior of Pa-12 Pipes Under Large Displacements by De Almeida LS, de Oliveira TA, Maurício MHP and d’Almeida JRM* in Crimson Publishers: Materials science Polyamide (PA) pipes are being increasingly employed in fluid distribution networks . Most of these pipes is used in underground networks, where overloads can cause large deflections. Excessive displacement can lead to product failure and can cause surface cracks and leakage of the fluid being transported. This condition can be maximized if the pipe is aged due to effects of the environment or of the fluid itself. In this work, the effect of aging PA pipe segments by their exposure to hot water is presented and discussed. The deformation characteristics of the material before and after aging are evaluated. The results indicate plasticization of the pipes due to exposure to hot water, and, thus, the loads required to cause a specific degree of compression, characterized by reduction of the pipe’s diameter, a...

Deformation Mechanisms in a NiobiumAdded Zirconium Alloy via Load Relaxation Tests_Crimson Publishers

 Deformation Mechanisms in a NiobiumAdded Zirconium Alloy via Load Relaxation Tests by Murty KL*, Webber KA and Charit I in Crimson Publishers Abstract:  Load relaxation tests have been performed on a recrystallized Nb-bearing Zr alloy sheet in the rolling direction at various temperatures. The strain rate - stress data thus obtained were used to identify the transitional deformation mechanisms in various modulus-compensated stress regimes. Crystallographic texture of the alloys that controls the extent of mechanical anisotropy was determined. Load relaxation tests are also performed in the direction at 45o to the transverse direction in order to characterize the deformation anisotropy. The degree of anisotropy (in terms of the strain rate ratio) is found to increase with the increase in stress exponent values. https://crimsonpublishers.com/eme/pdf/EME.000586.pdf For More open access journals in  Crimson Publishers please click on link:  https://crimsonpublisher...

Crimson Publishers-Analysis of Hybrid Power Train System Based on Degree of Freedom

Analysis of Hybrid Power Train System Based on Degree of Freedom by Kun Zhao in  Evolutions in Mechanical Engineering The hybrid power train is one of the most important technologies that have been developed to satisfy the challenging fuel economy and emission standards. A suitable configuration of hybrid power train should not only meet the requirements of vehicle kinematics and dynamics, but also meet the requirement of fuel economy and emission. For this purpose, a hybrid power train system should contain multiple power sources so that the speed and torque of the power sources can be properly distributed to achieve high system efficiency. To achieve optimal distribution of speed and torque, the system should have more speed DOF and torque DOF. Therefore, the hybrid power train system can be analyzed based on the viewpoint of degrees of freedom. https://crimsonpublishers.com/eme/fulltext/EME.000504.php For more open access journals in Crimson Publishers please ...
