INTRODUCTION:

A composite is a structural material that

consists of two or more combined

constituents are combined at a macroscopic

level. One constituent is called the

reinforcing phase and the other one is called

the matrix. A general classification of

different composite materials can be seen in

Fig 1. A schematic presentation of all

composites can be seen in Fig. 2 to have a

clear visualization. Composites are utilized

in a wide range of fields like mechanical,

aerospace, marine, automotive, biomedical

and MEMS due to their light weight, high

specific strength, high specific stiffness, and

excellent fatigue and corrosion resistance in

comparison to their conventional

counterpart. As discussed in the above lines

the composites have number of tailoring

properties and due to that many structural

components are fast replaced by composites.

Even though composites have distinct

features over conventional materials, they do

have few limitations or drawbacks. In

general, composites are flexible in nature as

compared to conventional material and

exposed to combined loading condition

which in turn affects their structural

behavior like vibration, bending and

buckling responses considerably. They may

suffer from large amplitude vibration and/or

large deformation early than the other

conventional material. To overcome the

above short comings many functional

(smart) materials (piezoelectric and

electrostrictive materials, shape memory

alloys, magnetostrictive materials, electro

and magneto rheological fluids etc.) are

developed in recent years. Each smart

material has a unique advantage and

disadvantage of its own in sensing, control,

and actuation. In the present analysis, out of

different functional materials

magnetostrictive material is taken due to its

unique property and wide applicability in

different industries. A brief discussion on

this material has been given in the following

paragraph.

1.2 Magnetostrictive materials and the

working principle

Magnetostrictive materials are probably the

most popular active material used in both

actuator and sensor applications because of

its low cost, low power consumption, low

weight, high frequency response and ease in

embedding or bonding with the structure.

According to James P.Joule (1842)

magntostrictive material is the smart

material which changes its magnetic state in

response to applied stresses when exposed to

a magnetic field. There are different

magnetostrictive (Terfenol-D, Galfenol etc.)

materials are available based on the required

application. In this present study, Terfenol- D is considered to be the magnetosrictive

smart material due to its relatively low

strains and moderate forces over a wide

frequency range serves as best commercial

magnetostrictive material available in the

market. The Terfenol-D has some dominant

advantages as actuators and sensors over

other materials. The coupled mechanical and

magnetic properties of magnetostrictive

smart make them well suited for use as

actuators and sensors in smart structures.

The direct and converse magnetic effect

governs the interaction between the

mechanicaland magnetic behavior of this

type of material. The direct magnetic effect

states that a strain applied to the material is

applied converted to magnetic field

intensity. On the other hand the converse of

magnetic effect states that a magnetic

intensity applied to the material is converted

to strain. The design and fabrication of large

complicated structures with integrated

magnetostrictive materials requires the

accurate modeling and analysis as

beforehand by using available analytical

and/or numerical method. Today design

engineers/engineering firms show

confidence on results of finite element

modeling and analysis either by the

commercial finite element package and/or

analysis of structures using customize code

using different computer language.

Terfenol-D is an alloy of terbium, iron, and

dysprosium and their application in today’s

engineering is given in Fig 3 and 4. It can

serve both as actuator and sensor and

produce strains up to 2500μm, which is 10

times more than a piezoceramic material. It

also has high energy density, negligible

weight, and point excitation with a wide

frequency bandwidth. As discussed

aforementioned paragraph, many research

works have been performed

successfully to simulate the various

linear/nonlinear responses of conventional

and composite materials using ANSYS

finite element software in recent years.

These studies show that ANSYS

can precisely simulate all sorts of material

and geometrical (linear/nonlinear) modeling

of laminated composite with and without

functional material. All types of

nonlinearities are allowed large

deformations, plasticity, creep, stress

stiffening, contact (gap) elements, hyper

elastic elements, and so on.
