Gamma-limit analysis of thin incompressible magnetoelastic shallow shells
What the study found The study characterizes the asymptotic behaviour of a thin incompressible magnetoelastic shallow shell using Γ-convergence, a mathematical notion for describing limiting behavior of variational problems. The compactness result is obtained up to rigid motions. Why the authors say this matters The authors state that the result generalizes a previous work by…
Analytical models predict stiffness and buckling of woven columns
—
in EngineeringWhat the study found The study found that purely analytical models can predict the buckling load and stiffness of woven columns. It also found that different buckling modes depend on the ratio of horizontal to vertical weaver width. Why the authors say this matters The authors conclude that the work advances understanding of the mechanics…
Fourier-Bessel uncertainty result for relatively dense sets
—
in EngineeringWhat the study found The authors show an analogue of the classical Paneah-Logvinenko-Sereda theorem for the Fourier-Bessel transform. In this setting, if a set E in the positive real numbers is relatively dense with respect to the measure μ_α, then the L2 norm of a function can be controlled by its L2 norm on E,…
