Abstract: Owing to the significant effects of adhesive force and surface/membrane tension, the classical contact models often fail to describe the indentation responses of soft materials and biological systems. This work addresses ...

Abstract: Residual stress can strongly affect the mechanical behaviors of engineering components. In this work, the authors revisit the role of equi-biaxial residual stress in the spherical indentation of elastoplastic solids by the ...

Abstract: Adhesion between a solid sphere and a thin film is a common but crucial issue in the study of biological membranes and two-dimensional materials. To supplement quantitative knowledge of membrane adhesion, this work addresses ...

Abstract: The conventional contact mechanics does not account for surface tension; however, it is important for micro- or nanosized contacts. In the present paper, the influences of surface tension on the indentations of an elastic ...

Abstract: The oscillatory indentation has become an attractive approach to characterizing the viscoelastic properties of soft biological solids. However, the influences of surface tension on oscillatory responses are ignored, which ...

Abstract: Investigating the contact of rough spheres is constructive to wide engineering applications and scientific research. However, the coexistence of global curvature and surface roughness brings difficulty in the analysis of ...
