sheet metal components design and manufacture need a great deal of experience and know-how. strip layout design is usually done with trial and error until best design for strip layout is finally achieved. knowledge for the system is formulated from plasticity theories, experimental results, and the empirical knowledge of field experts. in this paper, an algorithm which can automatically design ...

This paper presents a numerical investigation and statistical analysis of laser bending of Titanium sheets. The aim of the present simulation is to identify the response through response surface methodology related to bending angle and characterize the effects of input parameters: laser power, spot diameter, scanning speed and plate thickness. The numerical simulations are carried out based on ...

We have developed an efficient simulation technology for automotive wire harness design. Our technology consists of a layout design simulation and a bending simulation for wire harness. In addition, we have developed an efficient method for wire harness manufacturing design by the use of 3D CAD. These CAE technologies conclusively lead to front-loading of automotive development which is require...

Forming limit curves (FLCs) are important to predict failure against biaxial deformation in sheet metal forming. Particularly crucial is the detection and evaluation of stable/instable transition which indicates necking ultimately leads rupture. In past, it has been observed that specific processes, particular free-form bending might not be predicted well by conventionally evaluated FLCs, i.e. ...

The Linac Coherent Light Source (LCLS) is a SASE xray Free-Electron Laser (FEL) based on the final kilometer of the Stanford Linear Accelerator. One of the most critical diagnostic devices is the bunch length monitor (BLM), which is to be installed right after each compressor utilizing coherent radiation from the last bending magnet. We describe the components and the optical layout of such a B...

This paper offers a detailed, quantitative and exhaustive experimental comparison in terms of mechanical properties of three different layouts of carbon composite materials (CFRP) used to strengthen existing old timber beams highly affected by diverse natural defects and biological attacks, testing the use of pultruded laminate attached on the tension side of the element (LR), CFRP fabrics tota...

This paper presents an experimentally validated model for the computational analysis of metal-reinforced wooden composites. The can be used in both research and industry to effectively estimate how much a certain composite design improves bending stiffness strength hybrid component. A based on computer simulations allows prediction mechanical behaviour material consisting several interconnected...

The layout and the optical performance of the SGM branch of the D09 bending-magnet beamline, under construction at SESAME, are presented. The beamline is based on the Dragon-type design and delivers photons over the spectral range 15-250 eV. One fixed entrance slit and a movable exit slit are used. The performance of the beamline has been characterized by calculating the mirror reflectivities a...

Abstract This paper investigates the weight minimization of stiffened panels simultaneously optimizing sizing, layout, and topology under stress buckling constraints. An effective optimization parameterization is presented using multiple level-set functions. Plate elements are employed to model panels. The stiffeners parametrized by implicit internal topologies optimized as well their layout. A...
