To study the dynamic behavior and impact damage failure of concrete materials structures, a model was reformulated under framework non-local peridynamic theory in this paper. The stretch rate material bonds, equivalent to strain classical continuum mechanics, introduced, rate-dependent describing then proposed, taking both bonds rate-sensitivity evolution different into account. connection between strength tensile compressive established model. verify proposed for failure, several typical...
Strain hardening and strain rate play an important role in dynamic deformation failure problems such as high-velocity impact cases. In this paper, a non-ordinary state-based peridynamic model for damage of concrete materials subjected to impacting condition is proposed, taking the advantages both non-local method. The Holmquist-Johnson-Cook (HJC) describing mechanical character under large strain, high hydrostatic pressure was reformulated framework theory, corresponding numerical approach...
Porous metals are a new ultra-light material with high specific stiffness, strength, and good energy absorption properties. The elastic modulus plateau stress of porous essential parameters. There have been many studies on the effects matrix material, porosity, pore size metals, but few can be found impact arrangement. arrangement cannot quantitatively described, design space metal structure under same porosity is vast. With powerful learning prediction ability neural networks, influence...
In this paper, a nonlocal approach for handling nonlinear heat conduction problems is developed using the peridynamic differential operator (PDDO). The boundary conditions and equations are transformed from local form to integral by introducing functions. algebraic established Lagrange multiplier method variational analysis, which solved with Newton–Raphson iterative method. Nonlinearities resulting temperature-dependence of material properties have been taken into account in irregular...
Abstract Three-dimensional thermoelastic analysis of simply supported rectangular plates with variable thickness and subjected to thermomechanical loads is investigated. An approximate analytical solution method proposed. The temperature field the displacements are represented by a double harmonic series, respectively. First, heat conduction equation solved analytically obtain nonlinear series unknown coefficients. Then three-dimensional equilibrium differential equations displacement...
This work presents analytical solutions for bending deformation and stress distributions in functionally graded beams with arbitrarily continuously variable thicknesses resting on a two-parameter Pasternak elastic foundation. Based two-dimensional elasticity theory directly, the general of displacements stresses which completely satisfy differential equations governing equilibrium varying thickness are derived first time. The undetermined coefficients solution obtained using Fourier series...
