| Abstract | ||
| The residual strcss is that which remttns in a body thatis stationary and at cquilibHum with its surrclundings lt can be vcry dct五incntal to thc pcrfollllancc of a matcrial or thc lifc of a componcnt Altcrnativcly,beneflcial rcsidual strcsscs can be introduccd dclibcratcly Residual strcsscs arC mOrc difflcult to prcdict than thc in― cxpeHrnental incthods to scrvicc stresscs Thcrc arc rnany different measure thc rcsidual strcss such as holc dHlling and x― ray ln this paper,the new incthod is proposed to mcasurc thc residual strcss in weldment,this mcthod dcpends on thc strcss concentration factor for circle hole with different distance from weld line for different specimens (five specimens) , the hole is the region of measure the residual stress .Also , the heat treatment is applied for different specimens as same condision and dimention to measure the decrease in the stress .The results are in a good agreement with another method. | ||
