This passive integration is performed using multilayer ceramics technology, whereby green ceramic tapes of different materials - corresponding to the different passive functions - are laminated and co-fired usually at rather low temperatures with low loss and low melting point electrode such as Ag or Cu. [2].
Bismuth-based dielectric ceramics were well known as low-fired materials and had been investigated for the application as multilayer ceramics capacitors [3].

Introduction Since the advent and development of smart materials like optical fiber, shape memory alloy and piezoelectric materials, the role of a structure has become "smart", "intelligent" or "active" from "passive."
The piezoelectric material among smart materials is mainly used for the detection of acoustic emission (AE) signals or elastic waves which are generated by the rapid release of energy from the source such as cracks or damages within a structure.

Moreover, the material spectrum of AISF for structural parts is mostly restricted to cold workable materials like steel and aluminum.
The following technical advantages of laser-assisted AISF are expected: (i) increase in formability for sheet materials that are hardly cold-workable and (ii) extension of the geometry and application spectrum of AISF.

Moreover, the material deformation in primary shear zone during machining is a typical deformation process at high strain rate.
Experiment of machining A: Experimental Material AA 5083 was selected as the material work piece.
So this method to predict cutting force in machining for alloy 5083 and other materials are the machining features can be used.

An Upper-Bound Analysis of Closed Multi-Ram Forging of Rod Chundong Zhua, Chen Fub and Hui Wang c School of Materials Science and Engineering, Wuhan University of Technology, Wuhan, Hubei, 430070, China azcdzcd6252@sina.com, b fuchen19881111@126.com,c lianghappyhoho@sina.com Keywords: Upper-Bound Analysis; Closed Multi-Ram Forging; Deformation Load; Rod.
Multi-die forging can cut down the forging process and improve work efficiency; Multi-die forging doesn’t produce flash, so it can improve the mechanical property of material; Plasticity of material can remarkable raise with multi-die forging[2].
Fig.1.The archetype diagram of the rod Upper-bound analysis Before the analysis of upper-bound method[3],the deformable body and boundary conditions are simplified and assumed: Simplify the stress and strain state of the deformable body as axial problems or plane problems.[4] Invisible one is cut along the direction of metal flow in the deformed cross section and assume the role of the normal stress in their distributions is uniform principal stress; material is supposed to be incompressible and isotropic rigid-plastic material; the normal stress between mold and forging contact surface is supposed to be the main stress and shear stress conditions subject to Coulomb friction[5];Regardless of the elastic deformation of the mold and inertia.
The reason is that during the forming process, due to mold closing tightly enough, there is a gap which separating the upper and lower mold, so a little metal flow to the crevice formed boats side, and the depth of the flow of material mold cavity reduced.
