Nonlinear bending models for beams and plates. [PDF]
Proc Math Phys Eng Sci, 2014 A new nonlinear model for large deflections of a beam is proposed. It comprises the Euler–Bernoulli boundary value problem for the deflection and a nonlinear integral condition. When bending does not alter the beam length, this condition guarantees that the deflected beam has the original length and fixes the horizontal displacement of the free end ...

Bending-Induced Cross-Sectional Deformation of Cold-Formed Steel Channel-Section Beams
Advances in Civil Engineering, 2021 In practice, the cold-formed steel structures are widely used, and their geometrical nonlinearity is of great significance in structural design. However, the current analytical solutions are only applied to linear problems, and the nonlinear problems are

Nonlinear Elasticity of DNA Bending [PDF]
Biophysical Journal, 2012 Double stranded (ds) DNA has been used as a “molecular spring” to mechanically control the conformation of proteins, ribozymes and peptides [1]. It is thus interesting to characterize quantitatively the mechanics of DNA springs in the relevant regime of sharp bending ...
