WebApr 3, 2024 · At a macroscopic level, its stiffness and rigidity must be adequate to support the forces that the tissue usually suffers and must provide stability for the new tissue to grow. On the other hand, at a microscopic level, it must provide attachment sites, mechanical cues, and growth factors to cells to ensure their growth and proliferation ( O ... WebSep 13, 2009 · In particular, in many structures that have elastic responses, such as stems and arteries, the walls are in a state of tension generated by differential growth. Here, the effect of differential growth and residual stress on the overall mechanical response of the cylindrical structure is studied within the framework of morpho-elasticity.
