In the present study, the buckling analysis of the rectangular nanoplate under biaxial non-uniform compression using the modified couple stress continuum theory with various boundary conditions has been considered. The simplified first order shear deformation theory (S-FSDT) has been employed and the governing differential equations have been obtained using the Hamilton’s principle. An analytic...

The current clinical guidelines for the management of aortic abdominal aneurysms (AAAs) overlook structural and mechanical heterogeneity tissue its role in regional weakening that drives disease progression. This study is a comprehensive investigation biomechanical AAA along length circumference aorta, by means ex vivo properties. Biaxial testing histological analysis were performed on human sp...

Numerical simulations of cyclic biaxial tests were performed on samples with polygonal particles having aspect ratios (AR) equal to 1 up to 3 to better understand the cyclic behaviour of granular materials. The samples are created by deposit under gravity leading to the existence of an inherent anisotropy. Nevertheless, for the sample with AR equal to 1, numerical tests were also performed from...
