John E. Akin

Professor of Mechanical Engineering
Director of Graduate Studies

Research Summary

Dr. Akin's research applies the principles of finite element analysis techniques and associated error estimation that allows for adaptive analysis of problems in mechanical design, computational fluid dynamics (CFD), and orthopedic biomechanics.  He is also interested in optimization algorithms and their application to mechanical design.

For the last few years Dr. Akin has been carrying out CFD studies of the three-dimensional turbulent flows from non-axisymmetric nozzles. They have been shown to increase fluid entrainment by a factor of four, more than double the hydraulic horsepower imparted to the fluid jet, slightly increase the hydraulic impact force, and in some applications create a unique negative pressure on impingement surfaces. Applications to oil gas drilling showed they significantly increased the average rate of drilling penetration.  Applications to other fields such as mixing are now underway with a MS student.

Dr. Akin’s most recent research has been in the area of nonlocal damage mechanics in solids, its efficient implementation for low order finite elements, and the application of nonlocal damage mechanics to low cycle fatigue failure of metals.
