A 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 ...
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 ...
Special Section on Mechanics of Nanocomposites and Nanostructures
Publisher: American Society of Civil Engineers
Thermoelastic Modeling of Layered Composites Considering Bending and Shearing Effects
Publisher: ASCE
Abstract: Composite materials and structures often exhibit thermal stresses and deformations due to their thermal expansion mismatch. For a layered laminate, the stress transfer mechanism involves both bending and interfacial shearing, ...
Morphological, Thermal, and Mechanical Properties of Asphalt Binders Modified by Graphene and Carbon Nanotube
Publisher: ASCE
Abstract: The mechanical behavior of asphalt concrete varies with temperature; therefore, researchers have been developing technologies to reduce temperature fluctuations in pavement overlays. Increasing the thermal conductivity of ...
Preliminary Laboratory Evaluation of Methanol Foamed Warm Mix Asphalt Binders and Mixtures
Publisher: American Society of Civil Engineers
Abstract: The use of warm mix asphalt as an environmentally friendly alternative to hot mix asphalt is quickly building credibility and notoriety. Many technologies are being investigated that allow asphalt to be produced at a lower ...
Residual Stress and Opening-Mode Fracture Analysis of Multilayered Structures Subjected to Thermal Loading
Publisher: American Society of Civil Engineers
Abstract: Temperature change after formation commonly results in thermal residual stress in multilayered structures due to the different thermal and mechanical properties of each layer. In this paper, a three-dimensional (3D) elastic ...
