ABSTRACT
It is well known that a vast majority of problems found in engineering reality are not analytically solvable. There have been many simplified analytical solutions or empirical relations developed, some of which might be able to describe basic trends and provide estimates for engineering applications but might often miss technical details in many realistic aspects. Some other simplified approaches, on the other hand, have been proven to be way too simple, thus, have failed to satisfy today’s more demanding and challenging engineering requirements.
