solid mechanics

In this project, I will attempt to analyze the stresses and vibrations produced by a stroke of a golfer on the club in order to determine the drivers “sweet spot.”  The sweet spot is the spot on the clubface, which causes the lease amount of vibration and force transfer to the golfers hand thus giving the golfer the best energy transfer, feel and therefore, the best drive. (Cross, The Sweet Spot of a baseball bat)   Anyone who plays golf can quickly approximate the location of the sweet spot so I will attempt to verify its location through finite element analysis.

I found this paper on Vibrations of a Cantilever Beam.  Thought I would share it with the rest of the class.

Updated on 11 October 2008.  Each student creates a distinct project that (a) addresses a phenomenon, and (b) involves a serious use of ABAQUS.   To get some inspiration, see projects of students who took this course in the past.

The project contributes 25% to the grade, distributed as follows.

34. Surface acoustic wave device

35. Approximate a rod as a 2DOF system

36. Soft tissues: large difference in velocities of longitudinal and transverse waves

37. A general approach to determine body waves

38. Reflection and refraction of a transverse wave

1-1 ABAQUS Tutorial: Schedule & Proceedings

1-2 Learning ABAQUS: Begin with ABAQUS Command

1-3 Computer Assignment #1: Plate with circular hole

1-4 CAE Example: Having a sense of ABAQUS CAE

Notes on the stiffness matrix formulation, used for ES 120, Introduction to the Mechanics of Solids, a sophomore course. This material will not be covered in ES 240, but might provide helpful reading if you do not have this background.
