Size-dependent nonlinear bending of micro/nano-beams made of nanoporous biomaterials including a refined truncated cube cell

摘要: Abstract Morphology and pore size plays an essential role in the mechanical properties as well associated biological capability of a porous structure made biomaterials. The objective current study is to predict Young's modulus Poisson's ratio nanoporous biomaterials including refined truncated cube cells based on hyperbolic shear deformable beam model. Analytical relationships for are given function cell's dimensions. After that, dependency nonlinear bending behavior micro/nano-beams such analyzed using nonlocal strain gradient elasticity theory. It assumed that micro/nano-beam has one movable end under axial compression conjunction with uniform distributed lateral load. Galerkin method together improved perturbation technique employed propose explicit analytical expression load–deflection curves subjected transverse found through increment size, will undergo much more deflection corresponding specific load due reduction stiffness biomaterial. This pattern prominent lower value applied compressive at free micro/nano-beam.
