In this paper, aiming at the mechanics of tube hydroforming, the plasticity method was adopted in analyzing the stress yield behavior of the process. The stress character and yield behavior during the different stage of tube hydroforming was given and discussed. And then, basing on the discussing result, the yield behavior calculating formula was given and derived. At the same time, combining with the formula, figure of yield behavior was given. Base on the yield behavior character the process analysis was discussed in the end.

In the past decade, hydroformed structural components have been widely used in industrial areas in North American and Europe and there is a large potential market in Asia with the development of automotive industry. An extraordinary feature of tube hydroforming is that a hollow component with a three dimension axis and variable closed-sections can be integrally formed, so that the number of component parts is minimized, weight is reduced and stiffness of the part is increased. The section shapes in many automotive hollow components are complex and it is usually difficult or impossible to hydroform these typical sections directly from circular section tube, so that satisfactory preforms are necessary. In this paper, a method to reduce the friction and calibration pressure through a petal-like cross-section shape preform is presented and its mechanism is analyzed. Preforms for rectangular, trapezoidal and polygonal sections used in hollow components are investigated and satisfactory preforms are obtained. Taking an engine cradle as example, satisfactory preform section shapes have been designed, by which the thickness distribution was controlled and the flash generated from the die-parting surface in the final forming was avoided. So a carefully selected preform process can contribute significantly to the reduction of friction and calibration pressure and it is a dominant factor for successful hydroforming.

The marriage of the Tube HydroForming (THF) process with metal foams is interesting for different reasons: a) THF parts are naturally suited as cases to be filled by an internal metallic foam reinforcement and therefore for structural applications; b) the possibility to increase the mechanical strength of hydroformed parts allows to plan the THF process more freely and flexibly. These components, made of an outer hollow thin compact metal skin and a cellular lightweight core may find several applications in different industrial fields. In order to allow for an efficient and effective product/process design with a concurrent engineering approach, the structural performance of these composite parts must be predicted by means of FEM calculation. The optimal combination of tube and metal foam properties must be found. While FEM simulation of bending and hydroforming is state of the art, the accurate FEM simulation of the mechanical behavior of metal foams cannot be considered fully established. In the first part of this paper the foam-filling production cycle of a simple hydroformed aluminum part is shown, in order to discuss some of the design and manufacturing issues that can be faced in FEM based product/process analysis, concerning the thermal effects on the tube materials, the ability of completely filling the tube, the foam/tube interface conditions, the uniformity of cell distribution. A few potential applications of foam-filled hydroformed tubes are also presented. In the second part of the paper, the common methods and formulations for FEM simulation of foam based structures are discussed, and a new and very promising method is proposed.

Business Process Analysis can be used to eliminate or reduce a waste cost caused by non value added activities that exist in a process. This research aims at evaluating activities carried out in the natural material procurement process in the PT XYZ, calculating the effectiveness of the process cycle, finding a way to improve the process management, and calculating the cost reduction that can achieved by activity management. A case study was the approach of this research. The researcher obtained research data throughout deep interviews with the staff who directly involved in the process, observation, and documentation of natural material procurement. The result of this study show that the effectiveness of the process cycle of natural material procurement in the factory reached as much as 87,1% for the sand material and 72% for the crushed stone. This indicates that the process still carry activities with no added value and still contain ineffective costs. Through the Business Process Mechanism, these non value added activities can be managed so that the process cycle becomes more efficient and cost effectiveness is achieved. The result of the effective cycle calculation after the management activities implementation is 100%. This means that the cost of natural material procurement process has become effective. The result of calculation of the estimated cost reduction as a result of management activity is as much as Rp249.026.635,90 per year.
