RISA Novel Simple Solution to Cavity Expansion Problem in Crushable Granular Materials Based on Energy Dissipation Method
Publisher: ASCE
Abstract: This study presents an energy dissipation analysis approach for cavity expansion problems in crushable granular materials under the high stress state. By assuming that the energy dissipation generated from cavity expansion ...
Microstructure-Based Equivalent Visco-Hyperelastic Model of Viscoelastic Damper
Publisher: ASCE
Abstract: The mechanical properties of viscoelastic (VE) dampers directly affect the aseismic performance of viscoelastically damped structures; therefore, it is of great significance to accurately describe the nonlinear mechanical ...
Hyperelastic Hybrid Molecular Chain Model of Thermal-Oxidative Aging Viscoelastic Damping Materials Based on Physical–Chemical Process
Publisher: American Society of Civil Engineers
Abstract: The viscoelastic damping materials (VDMs) used in the viscoelastic (VE) damping equipment may undergo thermal-oxidative aging during long-time exposure to complicated working environments and exhibit significant property ...
Investigation of the Dynamic Properties of Viscoelastic Dampers with Three-Chain Micromolecular Configurations and Tube Constraint Effects
Publisher: American Society of Civil Engineers
Abstract: Molecular chain structures have important impacts on the damping performance of viscoelastic materials/dampers. In the present work, a microstructure mathematical model of viscoelastic dampers is proposed that relies on ...
