Courses for the 2015-2016 academic year

MS 115b. Fundamentals of Materials Science: Focus on Mechanical Behavior of Materials.
9 units (3-0-6); second term. Prerequisites: Graduate standing or MS 115a.

Review of Fundamentals in Structure and Bonding. Basic properties: Functional vs. Structural. Introduction to the mechanical behavior of solids, emphasizing the relationships between microstructure, defects, and mechanical properties. Elastic, anelastic, and plastic properties of crystalline and amorphous materials. Polymer and glass properties: viscoelasticity, flow, and strain rate dependence. The relations between stress, strain, strain rate, and temperature for deformable solids. Application of dislocation theory to strengthening mechanisms in crystalline solids. The phenomena of creep, yielding, and fracture, and their controlling mechanisms. Mechanical properties relevant to modern day: photovoltaic devices, thin films will be covered in MS/ME162.


MS/ME/MedE 116. Mechanical Behavior of Materials.

MS162 Videos:

Dislocation Climb by vacancy movement.

in situ TEM showing dislocations crossliping.

Animation showing a moving dislocation. Illustrates how the atoms accomodate the slip.

Dislocation Dynamics simulations showing the activiation of a single-arm source. These dislocations are pinned between a point in the cylinder and its surface.

Dislocations will not always move entirely at once. They often form a kink that is able to more easily pass across the potential landscape and then this kink propogates.

in situ TEM show an actual single-arm source that is generating dislocations in the crystal. They move towards the free surface and exit. From Marc Legros.

Showing a dislocation propogating and changing character between screw and edge.

in situ TEM tension test showing necking and nucleation of partial dislocation from the surface that then travel through the crystal.

Animation showing how a stacking fault propogates through a crystal. The green and red atoms are the top plane and the blue atoms are the bottom plane. The green atoms are the 'fault' in the stacking sequence and the region between the green and red atoms is the dislocation line.

Dislocation dynamics simulation showing strain hardening. The dislocation sources activate and glide through the crystal, reacting with each other and forming locks and creating a dense cellular structure.
