numerical analysis of thermo-mechanical coupling in shape memory alloys
the phase transformation phenomenon due to the crystallographic change of shape memory alloys subjected to mechanical or thermal loading is very complicated. regarding the thermo-mechanical coupling effects in shape memory alloys, in case of high loading rates, heat generation/absorption during the forward/reverse transformation, will lead in temperature-dependent variation and consequently af...
متن کاملNonlinear Thermo-Mechanical Behaviour Analysis of Activated Composites With Shape Memory Alloy Fibres
General thermo-mechanical behavior of composites reinforced by shape memory alloy fibers is predicted using a three-dimensional analytical micromechanical method to consider the effect of fibers activation. Composite due to the micromechanical method can be exposed to general normal and shear mechanical and thermal loading which cause to activate the shape memory alloy fibers within polymeric m...
متن کاملShape-Memory Polymer Composites
The development of shape-memory polymer composites (SMPCs) enables high recovery stress levels as well as novel functions such as electrical conductivity, magnetism, and biofunctionality. In this review chapter the substantial enhancement in mechanical properties of shape-memory polymers (SMPs) by incorporating small amounts of stiff fillers will be highlighted exemplarily for clay and polyhedr...
متن کاملShape memory micro-actuation for a gastro-intestinal intervention system
This paper describes the design of a prototype gastro-intestinal intervention system based on an inchworm-type of mobile robot. This type of device is a kind of vehicle for inspection through the colon, something that is currently impossible due to the large number of turns in the intestinal system. Eventually, tools for intervention can be added in the future. The overall system is about 95 mm...
متن کاملAn experimental investigation on the energy storage in a shape-memory-polymer system
In this paper, the effect of thermomechanical loading on the behavior of deflection-based harvested energies from a shape memory polymer system is experimentally investigated. Samples are created with honeycomb cells from poly-lactic acid using additive manufacturing techniques. The shape memory effect in shape recovery and force recovery paths are studied under thermomechanical tests in bendin...
