Analysis on Pseudo-steady Indentation Creep
Theoretical analysis and finite element (FE) simulation have been carried out for a constant specific load rate (CSLR) indentation creep test. Analytical results indicate that both the representative stress and the indentation strain rate become constant after a transient period. Moreover, the FE simulation reveals that both the contours of equivalent stress and equivalent plastic strain rate u...
متن کاملProblems of Structural Optimization Under Creep Conditions
Optimal structural design under creep conditions, initiated over 20 years ago, brings a fairly larg~ variety of problems, interesting both from theoretical and engineering point of view. Existence of the time factor leads to optimization for a prescribed lifetime and the number of independent variables in governing equations increases by one. Practical importance is connected with design of met...
متن کاملAnalysis of Steady State Creep in Short Fiber Composites (SFC) by Polynomial Function (PF) and Boundary Condition Method (BCM)
Two novel mathematical models based on polynomial function (PF) and boundary condition method (BCM) are presented for determination of shear stress in interface in steady state creep in short fiber composites under axial loading. Important novelty of this research is determination of shear stress in interface without using of shear lag and imaginary fiber technique (IFT) theories. In these appr...
متن کاملModeling of Steady State Creep in Thick-Walled Cylinders under Internal Pressure
Abstract—The present study focused on carrying out the creep analysis in an isotropic thick-walled composite cylindrical pressure vessel composed of aluminum matrix reinforced with silicon-carbide in particulate form. The creep behavior of the composite material has been described by the threshold stress based creep law. The values of stress exponent appearing in the creep law were selected as ...
متن کاملSteady State Creep Behavior of Functionally Graded Thick Cylinder
Creep behavior of thick-walled functionally graded cylinder consisting of AlSiC and subjected to internal pressure and high temperature has been analyzed. The functional relationship between strain rate with stress can be described by the well known threshold stress based creep law with a stress exponent of five. The effect of imposing non-linear particle gradient on the distribution of creep s...
