A Thermodynamical Constitutive Model for Shape Memory Materials. Part I. the Monolithic Shape Memory Alloy
Pseudoelasticity and the shape memory e ect (SME) due to martensitic transformation and reorientation of polycrystalline shape memory alloy (SMA) materials are modelled using a free energy function and a dissipation potential. Three di erent cases are considered, based on the number of internal state variables in the free energy: (1) Austenite plus a variable number of martensite variants; (2) ...
متن کاملCompression Analysis of Hollow Cylinder Basalt Continuous Filament Epoxy Composite Filled with Shape Memory Wire
This paper presents an experimental investigation into the compression behavior of shape memory alloy hybrid composites (SMAHC) subjected to quasi-static loading taking into account of rotation effects of shape memory wire in basalt continuous filament (BCF) direct roving epoxy composite. Two types of specimen prepared, the BCF direct roving reinforced epoxy composite filled with shape memory w...
متن کاملPolymeric triple-shape materials.
Shape-memory polymers represent a promising class of materials that can move from one shape to another in response to a stimulus such as heat. Thus far, these systems are dual-shape materials. Here, we report a triple-shape polymer able to change from a first shape (A) to a second shape (B) and from there to a third shape (C). Shapes B and C are recalled by subsequent temperature increases. Whe...
متن کاملEffect of shape memory alloy actuation on the dynamic response of polymeric composite plates
Dynamic properties such as the natural frequency of a structure have a significant role in the design process. The importance of this consideration is because of resonance. In this case, the amplitude of the vibration is magnified to levels that may lead to a catastrophic event. While the usual design process depends on the collected experiences and statistical data, a developing trend is to im...
متن کاملSEISMIC OPTIMIZATION OF STEEL SHEAR WALL USING SHAPE MEMORY ALLOY
Nowadays, steel shear walls are used as efficient lateral-load-resistant systems due to their high lateral stiffness and carrying capacity. In this paper, the effect of substituting a shape memory alloy (SMA) material is investigated instead of using conventional steel in the shear wall. A numerical study is conducted using finite element method (FEM) by OpenSees software. For this purpose, at ...
