Abstract: A method is proposed whereby the diffraction pattern produced by the distorted grating obtained from the Ligtenberg method can be suitably filtered to give lines of constant curvatures in ...

Abstract: The stress intensity factor of an interfacial crack in a bi-material can be represented by a complex vector whose phase changes as a function of r , the radial distance from a crack tip. ...

Abstract: The plastic deformation induced surface roughening mechanism of aluminum sheets is experimentally investigated. Specimens used in the study have grain sizes varying from tens of microns to ...

Abstract: By placing a moiré pattern behind the first field lens of an optical spatial processor its diffraction spectrum will be formed at the first image plane of the system. This diffraction spectrum ...

Abstract: Mechanical failure of machine parts, structures, and microelectronic components has a strong negative impact on the safety, security, and productivity of our people. Prevention of these failures ...

Abstract: In this paper, a modified shadow moiré technique is applied to measure surface topology of wafers. When a wafer is sliced, either by an inner-diameter (ID) saw or wiresaw, the surface needs ...
