RISA Simplified Continuum Particle Model Bridging Interatomic Potentials and Elasticity of Solids
Publisher: ASCE
Abstract: A continuum particle model correlates the interatomic potential of a crystal lattice with the elastic moduli of the solid, in which discrete atoms are modeled by perfectly bonded continuum particles, named singum, to ...
Improved Singum Model Based on Finite Deformation of Crystals with the Thermodynamic Equation of State
Publisher: ASCE
Abstract: The recently published simplified singum model has been improved by using the thermodynamics-based equation of state (EOS) of solids to derive a new interatomic potential based on elastic constants. The finite deformation ...
Elastic Solution of a Polygon-Shaped Inclusion With a Polynomial Eigenstrain
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the Eshelby’s tensor of a polygonal inclusion with a polynomial eigenstrain, which can provide an elastic solution to an arbitrary, convex inclusion with a continuously distributed eigenstrain by the ...
Elastic Solution of a Polyhedral Particle With a Polynomial Eigenstrain and Particle Discretization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper extends the recent work (Wu, C., and Yin, H., 2021, “Elastic Solution of a Polygon-Shaped Inclusion With a Polynomial Eigenstrain,” ASME J. Appl. Mech., 88(6), p. 061002) of Eshelby’s tensors for polynomial ...
Stress Concentration of a Microvoid Embedded in a Bilayered Material Considering the Boundary Effects
Publisher: American Society of Civil Engineers
Abstract: This paper extends Eshelby’s problem of one inhomogeneity embedded in a homogeneous infinite domain to a bimaterial infinite domain. The equivalent inclusion method (EIM) was used to simulate the inhomogeneity of an inclusion ...
Effect of Wrapping Force on the Effective Stiffness of Packed Parallel Wire Cables with Elastoplastic Contacts
Publisher: American Society of Civil Engineers
Abstract: When cables use many wires packed in a hexagonal pattern wrapped by bands around the surface, effective stiffness plays an important role in structural integrity and safety. This paper studies cylindrical wires packed in ...
Size Effect on Functionally Graded Material Fabrication by Sedimentation
Publisher: American Society of Civil Engineers
Abstract: A simple, economic, and scalable material manufacturing method of sedimentation has been used to fabricate functionally graded materials for solar roofing panels. This paper investigates the size effect of aluminum powder ...

Elastic Green’s Functions for a Specific Graded Material With a Quadratic Variation of Elasticity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, Green’s functions for unbounded elastic domain in a functionally graded material with a quadratic variation of elastic moduli and constant Poisson’s ratio of 0.25 are derived for ...
Time Series Prediction of Chimney Foundation Settlement by Neural Networks
Publisher: American Society of Civil Engineers
Abstract: Neural network (NN) models for time series forecasting were initially used in economic fields. In this paper, NN models for time series forecasting are introduced for use in forecasting the settlement of chimney foundations. ...
