Transverse shear modulus of elasticity for thin-walled corrugated cores of sandwich beams. Theoretical study

Ewa Magnucka-Blandzi, Krzysztof Magnucki
The subject of the paper are four corrugated cores in form of circular arcs, a sin wave, trapezoids and an odd function. Transverse shear modules of these corrugated cores are analytically determined. A comparative analysis of these transverse shear modules is presented. Areas of cross sections of the corrugated cores are constant. The theoretical study shows considerable sensitivity of the shear modulus to shape of the corrugation.
