Calculation of two-dimensional residual stress from total strain distribution.

CALCULATION OF RESIDUAL VOLUME BY SPIROMETRIC DATA

 ABSTRACT Background: The current practice to measure RV is either by BPG or helium dilution methods which may not be available in all clinics due to their cost. Methods: This paper outlines a method for both direct and indirect calculation of RV via PFT with acceptable sensitivity (81 %, 60% ), specificity (71 %, 94%) and validity (76%, 78%) for obstructive and restrictive lung disease respect...

Coating thickness effect on stress distribution of coated cylinder head considering residual stress

This paper presents the coating thickness effect on the stress distribution of a coated cylinder head. A typical thermal barrier coating was applied on a diesel engine cylinder head. Thus, the residual stress which occurred during the plasma thermal spraying was also considered. The coating system consisted of two layers a metallic bond coat and a ceramic top coat. The bond coat thickness is co...

Pattern of Residual Stress in Rail by FEM Analysis and Strain Gage Sectioning Technique

Final step of rail manufacturing is cold rolling straightening process and it hassignificant effects on mechanical properties, straightness, flatness and development of residualstresses. Measurement of residual stresses after straightening process is obligated by railmanufacturing standards. In the present investigation, an attempt has been made to evaluateresidual stresses after straightening ...

Residual stress distribution in rabbit limb bones.

The presence of the residual stresses in bone tissue has been noted and the authors have reported that there are residual stresses in bone tissue. The aim of our study is to measure the residual stress distribution in the cortical bone of the extremities of vertebrates and to describe the relationships with the osteon population density. The study used the rabbit limb bones (femur, tibia/fibula...
