SMA is a kind of super-elastic material and has been applied in many areas due to their high power density, solid state actuation, high damping capacity, durability and fatigue resistance.
The super-elastic deformation behavior of shape memory alloy was studied through material test, and its stress-strain curves were equivalent to multi-linear model (shown as Fig.2 and Fig.3).
The used steel was assumed to behave as an elastic plastic material.
This kind of element is a special element of ANSYS to represent the material property of SMA.

The challenge to the computer technology, science, and engineering is in handling these functions efficiently; and the key to doing so is in understanding the nature of the information that is being perceived, stored, processed, and presented.

(3) With different materials of heat exchanging pipes of under the same experimental flow velocity, the time when the fouling thermal resistance comes to be stable and the stable value are both different
(4) The surface treatment for heat exchange materials: many studies have shown that the use of surface treatment technology can play a role in anti-scaling, such as adopting nm surface coating, nitric acid passivity of the stainless steel, polished the surface of stainless steel.

In practice, the thickness of U-style steel slabs changes with the distribution of stresses for saving of steel material.
Calculation of horizontal shear force locating on the interface between the two materials is usually based on test data.
To steel-concrete composite plate 35~60% decrease of self-weight than its corresponding solid plate or two-way dense rib plate leads to several benefits: The maximum stress in steel-concrete composite plate is Fig. 8 A photo of test model of steel-concrete composite plate Fig. 9 Equivalent stress of a steel-concrete composite plate cut down by 25~45%, so we can save much of material; l The decrease of steel bars makes it easy to lay out steel bars that resist positive or negative moment; l To long-span RC structures the effect of self-weight is significant, steel-concrete composite plate makes it easy to control the deformation of plate; l The maximum bend moments of columns and substructures are also decreased; l The plate allures less seismic inertial force

Flexible hinge is a special driving structure, which utilize the tinny
elastic transmutation and recuperation character of elastic material to realize tinny displacement.
Differential part can be treated as equivalent cross-section rectangular beam with length of dx ; furthermore, the bending torque acting on the side of differential part is also the same, based on the "Material mechanics" the radius of curvature will be defined as: )( )(1 xEJ xM = ρ (1) Where E is modulus of elasticity; ρ is the radius of curvature; )(xJ is moment of inertia; )(xM is the bending moment on dx .
The 65Mn is chosen as flexible hinge material, one terminal of the hinge is fixed and the other one is put with the torque of 0.85N.M.
The material of flexible hinge is also 65Mn.

Abstract.
The material obtained by the technique was free of micropipes, with the etchpit density less than ~103 cm-2 beyond the seed contour.
Journal Title and Volume Number (to be inserted by the publisher) distribution along the crystal interface perimeter at the intermediate time instant t = 30 h (solid curve).
If local surface tangent αsurf is close to a close-packed plane (regions OA and BC), the terrace width is large and sparse material sinks (step edges) can not utilize most of Si and C adatoms.
The model can be readily extended to other bulk materials growing from the vapor, in particular, to group-III nitrides and II-VI compounds.
