Comparison of different numerical methods for calculating stress intensity factors in analysis of fractured structures
In this research, an efficient Galerkin Finite Volume Method (GFVM) along with the h–refinement adaptive process and post–processing error estimation analysis is presented for fracture analysis. The adaptive strategy is used to produce more accurate solution with the least computational cost. To investigate the accuracy and efficiency of the developed model, the GFVM is compared with two versio...
متن کاملDynamic Stress Concentration Factor in the Strip Plate with Fillet
Dynamic and static stress concentration factors ao, and as generated at a fillet part are observed by photoelastic method, and the comparison between two different factors is carried out. Next, the reflection coefficient A is calculated using the height of incident and reflected waves measured by the strain gauge. As the result, following relationship a= ( I+ A )as is derived experimentally. Th...
متن کاملAnalysis of electric signals of rock beams subjected to bending
Experimental laboratory work has been conducted to study electric signals of marble beams that have been subjected to three point bend tests. The specimens have suffered 12 abrupt loading steps up to failure and the corresponding BSC were recorded by means of copper electrodes placed in the lower surface of the sample. Alongside with the application of abrupt loading to the samples, BSC peaks w...
متن کاملStress Concentration Factors in Uniplanar Tubular KT-Joints of Jacket Structures Subjected to In-Plane Bending Loads
In the present research, data extracted from the stress analysis of 46 finite element models, verified using test results obtained from an experimental investigation, were used to study the effect of geometrical parameters on the chord-side stress concentration factors (SCFs) of central and outer braces in uniplanar tubular KT-joints of offshore structures subjected to four different types of i...
متن کاملVibration analysis of functionally graded cylindrical shells with different boundary conditions subjected to thermal loads
In the present work, study of the vibration of a functionally graded (FG) cylindrical shell made up of stainless steel, zirconia, and nickel is presented. Free vibration analysis is presented for FG cylindrical shells with simply supported-simply supported and clamped–clamped boundary condition based on temperature independent material properties. The equations of motion are derived by Hamilton...
