The model analysis indicates that when actin filaments in growth tend to actively drive the radial...

The objective of this study is to derive the exact matching condition consistent with a 5-DOF higher-order beam theory at a joint of thin-walled box beams under out-of-plane bending and torsion. Here we use bending deflection, bending/shear rotation, torsional rotation, warping, and distortion...

The constrained spring versus a freely rotating spring with the helix angle equal to π / 4 has the largest reduction in compliance in the limits of beam theory. Spring compliances for torsion...

The critical buckling strain of the double-wall carbon nanotubes is always between those for the inner wall and for the outer wall, which means that the vdW...

As the usual formulation of degenerated beam element is found to overestimate the torsional rigidity, an attempt has been made to reformulate it in an efficient manner. Moreover the new formulation...
