Bending of A Sandwich Beam With Thin Facesheets
The main assumptions of linear sandwich theories of beams with thin facesheets are:
- the transverse normal stiffness of the core is infinite, i.e., the core thickness in the z-direction does not change during bending
- the in-plane normal stiffness of the core is small compared to that of the facesheets, i.e., the core does not lengthen or compress in the x-direction
- the facesheets behave according to the Euler-Bernoulli assumptions, i.e., there is no xz-shear in the facesheets and the z-direction thickness of the facesheets does not change
However, the xz shear-stresses in the core are not neglected.

Famous quotes containing the words bending, sandwich, beam and/or thin:
“Sometimes we sailed as gently and steadily as the clouds overhead, watching the receding shores and the motions of our sail; the play of its pulse so like our own lives, so thin and yet so full of life, so noiseless when it labored hardest, so noisy and impatient when least effective; now bending to some generous impulse of the breeze, and then fluttering and flapping with a kind of human suspense.”
—Henry David Thoreau (1817–1862)
“The river’s tent is broken; the last fingers of leaf
Clutch and sink into the wet bank. The wind
Crosses the brown land, unheard. The nymphs are departed.
Sweet Thames, run softly, till I end my song.
The river bears no empty bottles, sandwich papers,
Silk handkerchiefs, cardboard boxes, cigarette ends
Or other testimony of summer nights.”
—T.S. (Thomas Stearns)
“It was at that moment, just after Krug had fallen through the bottom of a confused dream and sat up on the straw with a gasp—and just before his reality, his remembered hideous misfortune could pounce upon him—it was then that I felt a pang of pity for Adam and slid towards him along an inclined beam of pale light—causing instantaneous madness, but at least saving him from the senseless agony of his logical fate.”
—Vladimir Nabokov (1899–1977)
“Twilight and bulb define
the brown room, the overstuffed plum sofa,
the boy, and the girl’s thin hands above his head.”
—Muriel Rukeyser (1913–1980)
