Biography

Dr. Ahmed Abdelbary (A. Abdelbary) currently is a chief engineering and tribology consultant for the Egyptian government. He holds a B.Sc.(Eng.) from Military Technical College in 1994. He received his M.Sc. and Ph.D. in polymer tribology from Alexandria University in 2003 and 2011 respectively. Working with Prof. M.N. Abouelwafa, from 1999 to 2011, he explored tribological behavior of polymers under typical loading conditions and found many promising results. Much of this work obtained a better understanding of the fatigue wear mechanism of polymers. Currently he is investigating the effect of different fillers (Steel Slag and Graphite) on the tribological behavior of polymer composites.
He is a full member of the Egyptian Society of Tribology EGTRIB and received the title of "Engineering Consultant" from Egypt Syndicate for Engineers in 2016. His areas of technical and on-field expertise extend to design and manufacture of many mechanical and tribo-systems. His biography has been included in Who's Who in the World® 2015 (32nd Edition), and he lastly received the 2017 Albert Nelson Marquis Lifetime Achievement Award.
He is the author of two books; Wear of Polymers and Composites, Woodhead Publishing, Oxford, 2014, and Extreme Tribology, CRC Press, 2020. He is the author of several research papers on tribology of polymers, in well-reputed engineering journals. He has been appointed as one of the editorial board members in International Journal of Materials Science and Applications and Advances in Materials and a reviewer for many international journals.

Investigating Abrasion Resistance of Interlocking Blocks Incorporating Steel Slag Aggregate


Published: Jan 01, 2018 by ACI MATERIALS JOURNAL
Authors: Ahmed Abdelbary and Ashraf Ragab Mohamed

The object of the study is to investigate the possibility and the effect of replacing natural coarse aggregate in a concrete paving block with electrical arc furnace slag (EAFS) to enhance its properties. The effect of different mixing ratios of EAFS on abrasion resistance, compressive strength, and water absorption was evaluated. It is observed that all the mixtures achieved most of the required ASTM C936 limits.

Evaluation and prediction of the effect of load frequency on the wear properties of pre-cracked nylon 66

Subjects: Engineering - Mechanical

The present work focuses on the effect of load frequency on the wear behavior of a polymer with surface defects in dry sliding conditions. The defects were imposed vertical deep cracks perpendicular to the direction of sliding. Wear studies were conducted against a steel counterface at constant loads, and in cyclic loads at different frequencies. Artificial neural network (ANN) models were examined to identify one that optimally simulates wear under the applied load parameters.

The effect of surface defects on the wear of Nylon 66 under dry and water lubricated sliding

Subjects: Engineering - Mechanical

In polymeric bearing applications, it was found that the polymer tends to wear more quickly than indicated in laboratory wear tests. The reason has been attributed to the effect of loading conditions and the generation of fatigue surface cracks. The current study investigated the effect of a single imposed vertical crack in the Nylon 66 surface upon its wear behavior in dry and water-lubricated sliding conditions.

The effect of surface defects on the wear of Nylon 66 under dry and water lubricated sliding

Subjects: Engineering - Mechanical

Effects of crack orientation, under different static and cyclic loading parameters, on wear behavior were examined. Relative change in wear rate due to surface crack existence, as well as crack orientation, was studied to provide an understanding of surface fatigue wear. There was consistent evidence of the effect of surface crack on the wear rate under static and cyclic loading conditions.
