Microplane Constitutive Model and Computational Framework for Blood Vessel Tissue
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a nonlinearly elastic anisotropic microplane formulation in 3D for computational constitutive modeling of arterial soft tissue in the passive regime. The constitutive modeling ...
Microplane Model M4 for Concrete. II: Algorithm and Calibration
Publisher: American Society of Civil Engineers
Abstract: This paper represents Part II of a two-part study in which a new improved version of the microplane constitutive model for damage-plastic behavior of concrete in 3D is developed. In Part II, an explicit numerical algorithm ...
Lateral Confinement Needed to Suppress Softening of Concrete in Compression
Publisher: American Society of Civil Engineers
Abstract: Suppression of softening in the load-deflection diagram of concrete-filled tubular columns and spiral columns is proposed to serve as a design criterion helping to avoid the size effect and explosive brittle character of ...
Microplane Model M5 with Kinematic and Static Constraints for Concrete Fracture and Anelasticity. I: Theory
Publisher: American Society of Civil Engineers
Abstract: Presented is a new microplane model for concrete, labeled M5, which improves the representation of tensile cohesive fracture by eliminating spurious excessive lateral strains and stress locking for far postpeak tensile ...
Microplane Model M5 with Kinematic and Static Constraints for Concrete Fracture and Anelasticity. II: Computation
Publisher: American Society of Civil Engineers
Abstract: Following the formulation of the constitutive model in the preceding Part I in this issue, the present Part II addresses the problems of computational algorithm and convergence of iterations. Typical numerical responses ...
Diffusion-Controlled and Creep-Mitigated ASR Damage via Microplane Model. II: Material Degradation, Drying, and Verification
Publisher: American Society of Civil Engineers
Vertex Effect in Strain-Softening Concrete at Rotating Principal Axes
Publisher: American Society of Civil Engineers
Abstract: The inelastic behavior of concrete for highly nonproportional loading paths with rotating principal stress axes is studied. Test cylinders are first loaded in compression under uniaxial stress and then torsion is applied ...
Microplane Model for Fracturing Damage of Triaxially Braided Fiber-Polymer Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A material model for the fracturing behavior for braided composites is developed and implemented in a material subroutine for use in the commercial explicit finite element code ABAQUS . The ...
Size Effect on Strength of Laminate-Foam Sandwich Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments on size effect on the failure loads of sandwich beams with PVC foam core and skins made of fiber-polymer composite are reported. Two test series use beams with notches at the ...
Hyperelastic Anisotropic Microplane Constitutive Model for Annulus Fibrosus
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a recent paper, (2006, “An Anisotropic Hyperelastic Constitutive Model With Fiber-Matrix Interaction for the Human Annulus Fibrosis,” ASME J. Appl. Mech., 73(5), pp. 815–824) developed an ...
