TL;DR: In this paper, the authors reviewed the literature on the anticlastic curvature developed by beams and plates when subject to elastic and plastic bending, and reported some experimental investigations into the antic-lastic curve of plastically bent plates of varying widths and constant thickness for two materials, a mild steel and an aluminium alloy.

Quantum Entanglement: Where Dark Energy and Negative Gravity plus Accelerated Expansion of the Universe Comes from
TL;DR: In this paper, it was shown that the sum of both the dark energy of the wave and the ordinary energy of a particle is exactly equal to the energy given by the well known formula of Einstein E=mc2 which is set in a four-dimensional Kaluza-Klein spacetime.
Bending deformation of polyethylene solid
Koh-hei Nitta
Abstract: The moduli obtained from the three-point bending tests for beam and plate specimens are apparently higher than the tensile Young’s modulus. For the beam specimen, a volumetric compression mode is observed in the inner zone of the bent specimen, whereas a uniaxial tension mode is observed in the outer zone. The flexural modulus in beam bending can be determined using the bimodular model, where the moduli of the innermost and outermost layers represent the bulk and tensile moduli, respectively. On the other hand, plate bending results in a strip-biaxial deformation during bending, with the bending modulus obtained from the cylindrical deformation. The principal factor influencing the flexural moduli of both specimens is the Poisson’s ratio.

The bending of plate using a three-roll pyramid type plate bending machine
M B Bassett,W Johnson +1 more
TL;DR: An experimental three-roll pyramid type plate bending machine was constructed and measurements were made of the upper roll vertical force, the driving torque and the relaxed radius of curvature for a given disposition of the top and bottom rolls.

Anticlastic action of flat sheets in bending
TL;DR: A theoretical analysis of the stresses induced in thin elastic strips which are bent (by uniform bending moments) into arcs with substantially constant radii of curvatures is made in this paper. But this analysis assumes that the elastic strips have a uniform curvature.

Anticlastic behavior of flat plates: The mode of transverse distortion in a rectangular plate subjected to large longitudinal curvatures depends on the dimensionless parameter b2/Rt. Using a numerical technique, experimental results are shown to agree with theory for b2/Rt values up to 50
TL;DR: In this paper, a numerical procedure is developed, based on the trapezoidal rule, which determines the transverse deflections from the readings of strain gages mounted to the top and bottom surface of a rectangular plate subjected to large longitudinal curvatures.
