Electric features of dislocations
WebAn important feature of dislocations in ionic solids is that electrical charge effects can be associated with them. Dislocations in covalent crystals affect both mechanical and electrical properties. In materials with layer structures , slip occurs readily in planes parallel to the layers and is almost impossible in nonlayer planes. WebElectrical Injuries. Electrical injury is damage caused by generated electrical current passing through the body. Symptoms range from skin burns to damage to internal organs and other soft tissues, cardiac arrhythmias, and respiratory arrest. Diagnosis is based on history, clinical criteria, and selective laboratory testing.
