A Phenomenological three Dimensional Model for Pseudoelastic Behavior of Shape Memory Alloys

An unified viscoplastic model with internal kinematic variables is used to improve the description of the uniaxial and proportional loadings performed in the pseudoelastic range of shape memory alloys. There is a good agreement between experimental data and simulations. Moreover, this constitutive set of equations is efficient for the description of internal loops and the isothermal cyclic load...

Application of the Beam Theory to Model the Pseudoelastic and Ferroelastic Bending of SMA Beams

The study of simple beams made of shape memory alloys (SMA) is very interesting for industrial and experimental reasons. In this paper, it is realised using strength of materials' approach: different kinematical and behavioural assumptions are successively used to solve circular and three supports bendings' problems. The kinematical ones consist in taking into account small or large displacemen...

Constitutive Modeling of the Stress-Stretch Behavior of Two-Dimensional Triangulated Macromolecular Networks Containing Folded Domains

The mechanical behavior of the red blood cell membrane is governed by the lipid bilayer which resists changes in surface area and the underlying spectrin network which resists changes in shape. The constituent spectrin chains of the network consist of a series of domains along the chain, which exhibit noncovalent interactions. Upon sufficient extension of a chain, each folded domain undergoes m...

A thermomechanical model for a 1-D shape memory alloy wire with propagating instabilities

A thermomechanical boundary value problem and constitutive model are presented for a shape memory alloy (SMA) wire under uniaxial loading. The intent is to develop a one-dimensional continuum model of an SMA element that includes all the relevant thermomechanical couplings and is suitable for inclusion in finite element analyses. Thermodynamic relations are derived from phenomenological conside...

Mechanical Behavior and Constitutive Modeling of Metal Cores

Studying the mechanical behavior of metal cores provides insight into the overall performance of structures comprising metal sandwich plates, and can help immensely in designing metal sandwich plates for specific engineering applications. In this study, the response of folded (corrugated) plate and pyramidal truss cores are explored under both quasistatic and dynamic loadings. In particular, tw...
