Fracture Parameter Evaluation Using Digital Image Correlation Technique
Fracture and failure characterization of materials have been a crucial issue regarding reliable structural design. Stress Intensity Factor (SIF) is one of the most commonly used material parameters for more purpose. This study utilized Compact Tension (CT) Specimen test to determine mode-I SIF of polycarbonate material. Force, displacement and images of the near crack tip region were simultaneo...
متن کاملFull-field bulge testing using global digital image correlation
The miniature bulge test is an acknowledged method for characterizing freestanding thin films. Nevertheless, some discrepancies in the quantitative results from such tests can be found in literature, explained in part by erroneous assumptions in the analytical description used to compute the global stress and strain from the membrane pressure and deflection. In this research, a new method is pr...
متن کاملTowards Automation in Architectural Photogrammetry Using Digital Image Processing
This paper describes some approaches towards an automation in architectural photogrammetry using digital image processing. We present techniques for semi-automatic 3D measurement and the application of digital image analysis to support the extraction of facade primitives. The proposed semi-automatic 3D measurement is used for the determination of tie points for the orientation and the interacti...
متن کاملDisplacement monitoring of a Long-Span Arch Railway Bridge using Digital Image Correlation (DIC)
There is an escalating demand for condition monitoring enhancement of transport infrastructures worldwide. Bridges are of vital importance in transportation infrastructure and need such monitoring. In this research, a non-contact vision-based technique called Digital Image Correlation (DIC) was used to calculate the bridge displacements. A high frame rate camera with 4K capability was used for ...
متن کاملFracture toughness of dental composites determined using the short-rod fracture toughness test.
Plane strain fracture toughness (KIC) has been evaluated for a number of commercially-available dental composites. A modified Short-rod Fracture Toughness (SRFT) specimen design has been used, enabling small specimens to be tested conveniently. The effect on KIC of aging in water at 37 degrees C for seven days, one month, and six months has been determined for conventional, microfilled, and hyb...
