This work focuses on application of the laser forming process to NiTi shape memory alloys. While all NiTi shape memory alloys exhibit both superlasticity and the shape memory effect, this study is restricted to a temperature range over which only the superelastic effect will be active. Specifically, this work addresses laser forming induced macroscopic bending deformations, post process residua...

In this paper it is presented a mechanical study made on prototype parts created from aluminium and thermal conductive plastic. The scope to replace full metal used for cooling electronic control unit in automotive industry save costs. We plates plastic study. permanent bonding of two materials, without any glue or additional additives, can be obtained by applying heat an plate until around 300...

The dimpling process is a novel cold-roll forming process that involves dimpling of a rolled flat strip prior to the roll forming operation. This is a process undertaken to enhance the material properties and subsequent products' structural performance while maintaining a minimum strip thickness. In order to understand the complex and interrelated nonlinear changes in contact, geometry and mate...

Magnesium alloys are primarily used in aeronautical and automobile industry in wide variety of structural characteristics because of their favourable combination of tensile strength (160 to 365 MPa), elastic modulus (45 GPa), and low density (1 740 kg/m), which is two-thirds that of aluminium). Magnesium alloys have high strength-to-weight ratio (tensile strength/density), comparable to those o...

hot-melt extrusion is one of the most widely applied processing technologies in the plastic, rubber and food industry. today this technology has found its place in the array of pharmaceutical manufacturing operations. melt extrusion process are currently applied in the pharmaceutical field for the manufacture of a variety of dosage forms and formulations such as granules, pellets, tablets, supp...

Die performance and its service life is a non-trivial issue in metal forming industry as many factors in die life cycle from design, fabrication, to downstream service, all affect it. In this report, a simulation-based approach for die life estimation and improvement is developed by employing the FEM technology and metal fatigue theory. Using industrial part as case study, the validity, robustn...

With the development of plastic surgery techniques, computer aided approach has become a significant method in medical plastic surgery. In order to solve effects on surgical results made by the surface of a wound in craniofacial cosmetic surgery, accurate preoperative preparation is usually required for the surgery. This paper summarizes the application of computer aided technology in craniofac...

In order to achieve a high quality of metal forming process, material properties, velocity, stress and strain rate distribution have to be analysed very accurate. Several different approximate methods have been developed for the analysis of cold forming processes. In this paper the visioplasticity method is used to find the strain rate distributions from the experimental data, using the finite-...
