Inverse Approach to Evaluate the Tubular Material Parameters Using the Bulging Test
Advances in Materials Science and Engineering, Volume 2015, Issue 1, 2015., 2015 Tubular material parameters are required for both part manufactory process planning and finite element simulations. The bulging test is one of the most credible ways to detect the property parameters for tubular material. The inverse approach provides more effective access to the accurate material evaluation than with direct identifications.

Evaluation of CoBlast Coated Titanium Alloy as Proton Exchange Membrane Fuel Cell Bipolar Plates
Journal of Materials, Volume 2014, Issue 1, 2014., 2014 We investigated the potential of graphite based coatings deposited on titanium V alloy by a low‐cost powder based process for bipolar plate application. The coatings which were deposited from a mixture of graphite and alumina powders at ambient temperature, pressure of 90 psi, and speed of 20 mm were characterised and electrochemically polarised in 0.5

Science and Technology of Nuclear Installations, Volume 2013, Issue 1, 2013., 2013 This paper considers a composite cylindrical structure, with low‐enriched uranium (LEU) foil enclosed between two aluminum 6061‐T6 cylinders. A recess is cut all around the outer circumference of the inner tube to accommodate the LEU foil of open‐cross section.

International Journal for Numerical Methods in Engineering, Volume 125, Issue 11, 15 June 2024.Abstract Load modeling in nonlinear statics, particularly incorporating large deformations differs significantly from the treatment in linear analysis. As in structural dynamics masses in a gravity field generate the loading, their location, and their modifications within the deformation process must be considered in a nonlinear simulation.

Biaxial expansion due to compression experiments for measuring the failure strain of tubular samples
Strain, Volume 60, Issue 2, April 2024.Abstract The failure strain of a tube is a function of the biaxial strain ratio (axial strain/hoop strain) to which it is subjected. The relationship between failure strain and the strain ratio can be determined experimentally using expansion due to compression tests with a tensile load (EDCT), in which a ductile pellet placed inside the tube is ...
