Study of Mechanical Behavior and Deformation Field Characteristics of Sandstone under Cyclic Loading
نویسندگان
چکیده
The sandstone yield strength and tensile were increased under cyclic loading paths by using the Brazilian splitting method. experiment shows that (1) specimens exhibit multiple penetrating crack damage loading, while slightly increases; (2) horizontal strain (Exx) concentration area decreases, shear (Exy) increases form changes from completely brittle to ductile mixed tensile-shear damage; (3) mechanism of increase in specimen was explained digital image correlation (DIC) technique. results indicate a time lag occurs zone, penetration zone decreases effect, reduced stress leads specimens.

Numerical and Experimental Study on Ratcheting Behavior of Plates with Circular Cutouts under Cyclic Axial Loading
In this paper, accumulation of plastic deformation of AISI 1045 steel plates with circular cutouts under cyclic axial loading is studied. Loading was applied under force-control conditions. Experimental tests were performed using a Zwick/Roell servo hydraulic machine. Under force-control loading with nonzero mean force, plastic strain was accumulated in continuous cycles called ratcheting. Nume...
متن کاملSubstructure 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 کاملNumerical and Experimental Study on Ratcheting Behavior of Steel Cylindrical Shells with/without Cutout Under Cyclic Combined and Axial Loading
Ratcheting behavior of steel 304L cylindrical shell under cyclic combined and axial loading are investigated in this paper, numerically. Cylindrical shells were fixed oblique at angle of 20° and normal with respect to the longitudinal direction of the shell and subjected to force-controlled cycling with non-zero mean force, which causes the accumulation of plastic deformation or ratcheting beha...
متن کاملComparison of Radial Consolidation Behavior of Clay under Three Types of Cyclic Loading
Vertical drains and stone columns which have been used in infrastructure construction for highways, ports, coastal regions, etc., provide significant benefits for improving soil characteristics such as reducing the drainage length and accelerating the consolidation process. So the investigation of the radial consolidation is inevitable. Soils may be subjected to cyclic loading such as silos, ta...
