Local One-Sided Rubber Bulging Test to Measure Various Strain Paths of Metal Tube

open access: yesMetals, 2021
We proposed a local one-sided rubber bulging method of metal tubes to evaluate various strain paths at an aimed portion and measured the forming limit strains of metal tubes at the place of the occurrence of necking under biaxial deformation.

Investigation of the effect of using geogrid, short glass, and steel fiber on the flexural failure of concrete beams

open access: yesAlexandria Engineering Journal, 2023
This research studies the flexural behavior of concrete beams reinforced with biaxial geogrids, distributed short glass and steel fibers. No longitudinal steel reinforcement bars were used. Therefore, an amount of short glass and steel fibers was used to

New Multistage Sheet-Bulk Metal Forming Process Using Oscillating Tools

open access: yesMetals, 2020
A new sheet-bulk metal forming process for the production of bulk components out of a flat sheet has been developed. Superimposed oscillation has been applied to the new process. By this means, process limits regarding better mould filling were expanded,
