NURSERY RHYMES ABOUT COMPOSITES
In Fall 2012, I asked the students in the class to write a poem based on the nursery rhyme One Two, Buckle My Shoe. They were asked to fill in the blanks for the following outline.
One, two,
One, two,
One, Two Tsai Hill breakthrough Three, Four based on Von Mises lore Five, Six considers distortion energies ethics Seven, Eight failure mode state put to stalemate Nine, Ten lets put this theory to use as a swordsmen
One Two I go to class, I know the clue Three Four It’s a course in fall, Taught by Dr. Kaw Five Six A composite is reinforced by fibers, Embedded by matrix Seven Eight It’s high in strength, and light in weight Nine Ten It’s of use a lot, but when it fails, it cannot be amend.
One, two, Composites? I don’t have a clue! Three, Four, Polymer, metal, ceramic matrices and more Five, six Compliance, stiffness, and transformation matrix Seven, eight Needed to find properties of lamina and laminate Nine, ten Qbar, Sbar, o how to use them and when!
One, two,
find TsaiWu,
strain failure
burn matrix,
from laminate, volume fraction,
One, two,
this a big move
at least two factors
fiber and matrix
make it a laminate that's like a blend
One, two, c’mon y’all we got math to do Three, four, what are the contributing fiber factors Five, six, time to study a polymer matrix Seven, eight, analyze the lamina to laminate Nine, ten, check it, stickum with epoxy resin (wicka wicka)
One, two,
One, two
One, two Choose TsaiWu. Three, four It’s for sure Five, six To be the mix Seven, eight Of postulate Nine, ten Or data bin.
One, two, Composites make up my shoe. Three, four, Recycling composites is a chore. Five, six, With composites, try no tricks. Seven, eight, New materials we will create. Nine, ten, Experiments and theory, together again.
One, two, composites taught by Dr. Kaw Three, four, helpful for sure Five, six, fiber and matrix Seven, eight, stiffness and strength Nine, ten,
One, two, Isotropic assumptions will not due. Three, four Calculating Qbar is a bore. Five, six An example of composites is straw in bricks. Seven, eight Composites are useful due to their weight. Nine, ten Hybrid laminates result in a blend of reinforcing phases or matrix systems.
