RISCharacterization of Interfacial Properties of Graphene-Reinforced Polymer Nanocomposites by Molecular Dynamics-Shear Deformation Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present an approach for characterizing the interfacial region using the molecular dynamics (MD) simulations and the shear deformation model (SDM). The bulk-level mechanical properties of graphene-reinforced ...
Inverse Estimations of Dynamic Stiffness of Highway Bridge Embankment from Earthquake Records
Publisher: American Society of Civil Engineers
Abstract: In this paper, the dynamic self-optimizing inverse method (Self-OPTIM) has been proposed to inversely estimate model parameters by using structural responses under dynamic loadings such as earthquakes. The proposed dynamic ...
Improved Damage Localization and Quantification Using Subset Selection
Publisher: American Society of Civil Engineers
Abstract: Because a structure’s modal parameters (natural frequencies and mode shapes) are affected by structural damage, finite- element model updating techniques are often applied to locate and quantify structural damage. However, ...
Improved SelfSim for Inverse Extraction of Nonuniform, Nonlinear, and Inelastic Material Behavior under Cyclic Loadings
Publisher: American Society of Civil Engineers
Abstract: In this paper, an improved self-learning simulation (SelfSim) method is proposed for the inverse extraction of nonuniform, inelastic, and nonlinear material behavior under cyclic loadings. The SelfSim has been used to ...
