Plesae explain your answers, thanks. Consider point/linear/surface defects: 1. Dislocations in metals are example of which defect? 2. Dislocations in plastics are example of which defect? 3. Dislocations in ceramics are example of which defect? Solution 1)Dislocation in metals are the example for linear defects.When stress is applied to the metals it deforms linearly to side ways or at edges etc so it is an example of linear defects 2)Dislocation in plastics are example for surface defects 3)Dislocation in ceramics are example for surface defects.
