Buckling Behavior of Composite Plates with a Pre-central Circular Delamination Defect under in-Plane Uniaxial Compression
Delamination is one of the most common failure modes in composite structures. In the case of in-plane compressional loading, delamination of a layered flat structure can cause a local buckling in delaminated area which subsequently affects the overall stiffness of the initial structure. This leads to an early failure of the overall structure. Moreover, with an increase in load, the delaminated ...
متن کاملProbabilistic Models for Defect Initiated Fracture in Ceramics
Fracture tests on hot-pressed silicon nitride containing voids and sevet·al types of inclusions have been conducted. Fracture models pertinent to each defect type have been proposed and correlated with the data. The specificity of the fracture models is emphasized, and the various trends with defect size that result from the models are described. The resultant fracture probability relations are...
متن کاملApplication of air – coupled ultrasonic technique for sizing of delamination type defect in multilayered materials
Ultrasonic testing using couplants is most popular technique for non destructive testing of solid materials. In the most non – destructive evaluation tasks such as investigation of materials whose properties may be changed by liquid contact this technique can not be used. Use of contact technique can be restricted for complex geometry structures. Also, liquid couplants cannot be used when mater...
متن کاملUsing SF6 Decomposed Component Analysis for the Diagnosis of Partial Discharge Severity Initiated by Free Metal Particle Defect
The decomposition characteristics of a SF6 gas-insulated medium were used to diagnose the partial discharge (PD) severity in DC gas-insulated equipment (DC-GIE). First, the PD characteristics of the whole process were studied from the initial PD to the breakdown initiated by a free metal particle defect. The average discharge magnitude in a second was used to characterize the PD severity and th...
متن کاملCapsulorrhexis in capsular delamination.
Separation of the anterior layer of the lens capsule, also known as true exfoliation and capsular delamination, has become an increasingly rare clinical finding. Although its pathogenesis is not precisely known, the condition has been associated with age, trauma, and exposure to toxins and/or to thermal radiation. An association with occupational infrared radiation exposure was accepted after E...
