Structure-Analitycal Theory of Martensitic Unelasticity

Structure-Analitycal Theory of Martensitic Unelasticity

The article presents a theory able to calculate various phenomena of martensitic unelasticity as well as of dislocation plasticity. The theory is based on the structure-analytical conception. The developed lnethodology accounts for such fundamental phenomena as kinetics of martensite crystals growth; influence of temperature, stress and neutron radiation; influence of nonhomogeucons strain of d...

Principal Concepts of Martensitic Theory

Fundamentals of the theory of martensitic transformations are discussed. Principal theoretical concepts which are valid for all phase transformations in solids are formulated and illustrated. Some basic problems which are still unsolved are pointed out.

Structure and evolution of martensitic phase boundaries

This work examines two major aspects of martensitic phase boundaries. The first part studies numerically the deformation of thin films of shape memory alloys by using subdivision surfaces for discretization. These films have gained interest for their possible use as actuators in microscale electro-mechanical systems, specifically in a pyramid-shaped configuration. The study of such configuratio...
