Substructure Model for Concrete Behavior Simulation under Cyclic Multiaxial Loading
This paper proposes a framework for the constitutive model based on the semi-micromechanical aspects of plasticity, including damage progress for simulating behavior of concrete under multiaxial loading. This model is aimed to be used in plastic and fracture analysis of both regular and reinforced concrete structures, for the framework of sample plane crack approach. This model uses multilamina...
متن کاملMultiaxial high-cycle fatigue criterion and life prediction for metals
A new high-cycle fatigue criterion based on the critical plane approach is proposed in this paper. Unlike most of the other multiaxial fatigue criteria based on the critical plane approach, the critical plane is directly correlated with the fatigue fracture plane. The proposed criterion has a wide range of applicability from very ductile metals to extremely brittle metals. Mean stress effect is...
متن کاملVertical Contraction Joint Models for Nonlinear Dynamic Analysis of Concrete Arch Dam
Arch dams are generally built in cantilvever monoliths. Vertical contraction joints between monoliths control the stresses due to concrete shrinkage and temperature variations. Past studies in earthquake safety evaluation of the system often show the tensile fracture and local nonlinear deformation of joints. In this paper, some nonlinear joint element constitutive models are presented to exami...

متن کاملEstimating the Strength of Concrete Using Surface Rebound Value and Design Parameters of Concrete Material
This study estimates the strength of concrete, an attempt is also made to increase the accuracy of Calculating the strength, using the nondestructive test (NDT) surface hardness rebound value, material design parameters and regression analysis. The strength of the concrete specimens was 130 480 kgf/cm, and their ages were 7 38 days. In total, 166 standard specimens of concrete were grouped into...
