Material Strength
These sponges skeletons have amazing geometric configurations, which have been extensively studied for their stiffness, yield strength, and minimal crack propagation. An aluminum tube (aluminum and glass have similar elastic modulus) of equal length, effective thickness, and radius, but homogeneously distributed, has 1/100th the stiffness.

Famous quotes containing the words material and/or strength:
“We all drew on the comfort which is given out by the major works of Mozart, which is as real and material as the warmth given up by a glass of brandy.”
—Rebecca West (1892–1983)
“Why, therefore, should we do ourselves this wrong,
Or others—that we are not always strong—
That we are sometimes overborne with care—
That we should ever weak or heartless be,
Anxious or troubled—when with us is prayer,
And joy and strength and courage are with Thee?”
—Richard Chenevix Trench (1807–1886)
