Indentation technique Notch-tip region Plastic damage True stress-true strain curve
In the present study, a semi-destructive method for estimating the mechanical properties, including plastic strain, of materials was developed using the instrumental indentation technique (IIT). The formula for estimating plastic strain was derived using true stress-true strain curves that were measured by IIT. The developed method requires only one parameter, namely, the work hardening coefficient, for estimating the plastic strain of pre-strained materials. The usefulness of the developed method was ...

Angular distortion Measurement experiment Numerical simulation Reverse-side heating
It is known that weld distortion has negative influence on structure integrity. Therefore, it is important for ensuring structure strength and reliability to control weld distortion appropriately. Especially, development of various countermeasures against weld distortion is desirable for emergent repair work in large-scale accident such as earthquakes. As one of useful countermeasure against angular distortion, in-process control welding with reverse-side heating was proposed however validation of the ...
