Liquid Cavitation during Nitrogen Sorption on Soils
(ASCE, 11/1/2021)The nitrogen sorption isotherm is conventionally used to deduce the specific surface area of porous materials. However, it often exhibits a sharp drop around 0.5 relative pressure. A theory explicitly accounting for ... -
Experimental Characterization of Frictional Line Contact by Digital Image Correlation and Inverse Method
(ASCE, 11/1/2021)Line contact usually causes stress concentration, resulting in the wear and failure of materials and structures. The characterization of the contact phenomenon thus plays an important role in the safety evaluation of ... -
Linking the von Karman Equations to the Practical Design of Plates
(ASCE, 11/1/2021)The Föppl-von Karman equations describe the highly nonlinear postbuckling behavior of elastic plates but are notorious for their unwieldiness. Owing to the lack of a sufficiently general solution, the practical design of ... -
Two Approaches to Quantification of Force Networks in Particulate Systems
(ASCE, 11/1/2021)The interactions between particles in dense particulate systems are organized in force networks, mesoscale features that influence the macroscopic response to applied stresses. The detailed structure of these networks is, ... -
Origami Metamaterials with Near-Constant Poisson Functions over Finite Strains
(ASCE, 11/1/2021)Origami-based structures have gained interest in recent years due to their potential to develop lattice materials, called metamaterials, the mechanics of which are primarily driven by the unit cell geometry. The folding ... -
