Paper Abstract

New methods of deformation analysis using electronic speckle pattern interferometry is proposed. The advantages of the measurement system are its capability to evaluate the phase data embedded in fringe pattern continuously, by simply taking speckle images and doing simple arithmetic operation on data processing stage. The methods can be applied for deformation analysis and fracture prediction technique on a loaded material. Analysis of fracture was done based on mesomechanics theory proposed by V. E. Panin. The important strength of this system is the ability of predicting a future crack on a loaded material by performing non contact and non destructive measurement system.
