please explain each of this option and which one is correct.
Elastic deformation of a crystalline solid.
Plastic deformation in an amorphous solid.
Incorrect! Correct Answer : Plastic deformation of a crystalline solid.
Plastic deformation of a crystalline solid.
Elastic deformation of an amorphous solid.
1, 2, 4 and 5 are correct.
please explain each of this option and which one is correct.
Explanation / Answer
islocation motion is defined as the stress that makes a dislocation happen in a solid material if the stress is removed then the dislocation motion can be reversed or not.
In elastic deformation the dislocation is reversed in both amorphous or crystalline materials
Plastic deformation in amorphous material the deformation information is not carried forward as the material does not have long range order so this is can be thought of as a stress based phenomenon which reverses back.
Only in the case of plastic deformation in crystalline material a real defect is created.
So in the true sense
Dislocation motion is associated with
Elastic deformation of a crystalline solid.
Plastic deformation in an amorphous solid.
Elastic deformation of an amorphous solid.
These 3 are correct
