ABSTRACTStructural Porous Metals (SPM) was specifically designed to offer large weight reductions in structural applications. The pores of gas are incorporated into the SPM during hot isostatic pressing. Since the gas in the pores are at high pressure and are closed isolated pores, SPM can be processed by standard methods such as rolling or forging without collapsing the gas pores. The objective of this paper is to show that the combination of computer simulation and intrinsic workability modeling provide a rapid and cost-effective way, for understanding the process and selecting the process parameters. This paper explains how SPM material data and developed material density updating scheme can be used in conjunction with the existing theory and FEM model.

Verification, validation, and testing (VVT) are the primary means of risk reduction in the product development process. Through systematic and early VVT strategy planning and continuous monitoring of the product development activities rework can be avoided and significant product lifecycle cost reductions can be achieved. In this paper a VVT process modeling procedure is described, which offers an effective method for reducing programmatic and technical risk through providing valuable assistance in the VVT strategy planning process. Programmatic risk reduction in the VVT process modeling procedure can be achieved by the elimination of redundant VVT activities, optimization of test schedule and restructuring of VVT activities into clusters based on the input needs of the tests and the deliveries of the product development activities. Through iterations in the VVT process during VVT strategy planning, the most effective combination of VVT activities can be found for the VVT goals and objectives. Iterations in the VVT process modeling procedure can be made based on the different durations, costs and effects on quality of the different VVT activities and methods applied at different points in the product lifecycle. Since the VVT strategy planning is an iterative process, the VVT process modeling procedure can be used to update the VVT process after every critical decision and milestone in the product development. The modeling concept for verification, validation and testing processes introduced in this paper, is currently being developed in a European research project, called SysTest (more information on the SysTest project can be found under: http://www.secoe.org/0105.htm).

This article provides an overview over some current challenges in industrial composite product development with a main focus on numerical analysis. Three main subjects are covered. Firstly, sizing of composite joining techniques is discussed with an emphasis on the joining of thin ply laminates. Secondly, multi scale analysis, determination of nesting factors and optimization of braided composite structures is discussed. Finally, a shape optimization approach for embedded SHM sensors, aiming at improving the mechanical properties of monitored laminates, is presented.

Product development process modeling (PDPM) is one of the key techniques for product development (PD). The main aim of PDPM is to provide a product design chain (PDC) for PD. To increase the efficiency of PDPM, a project-driven e-design system is proposed in this paper. There are two modules in the system: task decomposition and product design chain construction. Additionally, key techniques for enabling the system are discussed. Finally, an example of steering oil pump design project is studied to demonstrate the system.

Process modeling of Cooperative Product Development (CPD) is the key of CPD process management. Analyzing the process of developing production based upon Petri Nets, referring to workflow management and combining with parallel project, a new workflow modeling method based upon layered timed color Petri nets is invented, which supports the developing of the model production that parallels CAD/CAPP. Finally taking the developing CDP of model product as an example, workflow model has been designed and has been inspected and verified in the software platform.
