ML3013 MICRO AND NANOMECHANICAL PROPERTIES OF MATERIALS LT P C
3 0 0 3
OBJECTIVES
Many materials have different properties on a micro and nano scale as compared to bulk
material. This difference and special properties only relevant to nano scale material are
elaborated on in this course and should be mastered by the students.
UNIT I INTRODUCTION 5
Overview of the composition, structure, chemical and mechanical properties of surfaces
and how these properties affect mechanical and tribological properties of surfaces.
UNIT II MICROMECHANICS 5
Multiscale interactions between surfaces; fractal nature of surface topography; interfacial
forces, adhesion, and principles of micromechanics; techniques for surface
characterization.
UNIT III DEFORMATION MECHANISMS 15
Stress and strain of material; Elastic deformation: Young’s modulus, Poisson’s ratio,
stress-strain relation, stiffness/compliance matrix; Dislocations: Edge/screw/mixed
dislocation, burgers vectors, twining, stress field of dislocation, dislocation interaction;
Plastic deformation of single and polycrystalline materials: Schmid’s law, plastic flow;
Inelastic deformation: Viscosity, deformation of inorganic glasses, deformation of
nanocrystalline and crystalline polymers; Mechanical fracture: ductile and brittle facture,
creep, fatigue;
UNIT IV TESTING METHODS 5
71
Various Testing methods - Experimental determination of Mechanical Properties –Types
of Hardness testing of Metals and Strength of Metals, Polymers, Ceramics and
Composites.
UNIT V NANOMECHANICAL PROPERTIES 10
Determination of surface mechanical properties (AFM/nanoindentation), simple friction
theories - effects of surface composition and structure on friction, environmental and
temperature effects, relationship with surface chemistry, mixed and boundary lubrication,
failure mechanisms
TOTAL : 45 PERIODS
