Tensile Stress Driven Surface Wrinkles on Cylindrical Core–Shell Soft Solids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It has been experimentally observed that wrinkles formed on the surface of electrospun polymer nanofibers when they are under uniaxial tension (Appl. Phys. Lett., 91, p. 151901 (2007)). Molecular dynamics (MD) simulations, ...
Variable Chain Confinement in Polymers With Nanosized Pores and Its Impact on Instability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent experiments and molecular dynamics simulations have proven that polymer chains are less confined in layers near the free surfaces of submicronnanosized pores. A recent model has incorporated this observed variable ...
Contact Model for Incompressible Neo-Hookean Materials Under Finite Spherical Indentation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a contact model is proposed to predict the contact response of an incompressible neo-Hookean half-space under finite spherical indentations. The axisymmetric finite element (FE) model is created to simulate ...
