Question:
In order to model dislocations in elastic solids, multivalued displacement fields are necessary. As shown later in Chapter 15, for the particular case of a screw dislocation the displacements are given by:
where b is a constant called the Burgers vector. Show that the strains resulting from these displacements are given by:

I have done job as Embedded System Engineer for just four months but after it i have decided to open my own lab and to work on projects that i can launch my own product in market. I work on different softwares like Proteus, Mikroc to program Embedded Systems. My basic work is on Embedded Systems. I have skills in Autocad, Proteus, C++, C programming and i love to share these skills to other to enhance my knowledge too.
