A model for material damping is presented in terms of internal friction and in terms of a variation of stiffness. In the latter case the idea is that the stiffness increases if elastic energy is stored and decreases if elastic energy is released. In case of a single mass spring system ... Per saperne di più
Micro impact extrusion is investigated at Chemnitz University of Technology as a potential procedure for large area machining of micro cavities within the scope of the SFB/Transregio 39 PT-PIESA of the German Research Foundation. Applying impact extrusion micro forming is done by ... Per saperne di più
The increasing demand for improved metallurgical products strongly motivates the optimization of manufacturing processes and design of γ-TiAl products. Among the large variety of available forming processes, cold closed-die forging is particularly suitable for producing net shape ... Per saperne di più
An attempt was made, as described in this paper, to assign material properties like shear strength and modulus of elasticity randomly. In this way, the behaviour of a masonry wall with a prefabricated concrete lintel was experimentally tested and simulated using COMSOL. The paper ... Per saperne di più
The press and blow (P&B) process is widely used to produce glass containers. While the P&B process has demonstrated to be capable of reducing container weight by as much as 33%, it can also induce the formation of micro-checks that weaken container strength. This paper presents ... Per saperne di più
The present work formulates the dynamics of a slender structure as a long beam. This results in a PDE that is fourth-order in space, and second order in time. In COMSOL the coupling method is used to decompose this problem into two second-order equations, one for displacements, and one ... Per saperne di più
The application of shape memory alloys (SMA) as actuators in smart structures is a quickly developing field. The particular focus of this paper is on the aspects of modeling and simulation of adaptive structures with integrated SMAs using the finite element method (FEM). A number of ... Per saperne di più
Strained technology is being promoted as the best way to extend the performance of semiconductor transistors. An inhomogeneous layer deposited on top of a silicon device can induce a strong modification in the real silicon strain state, and consequently in its electronic performance. ... Per saperne di più
Among the several types of capacitors, the double-layer and redox types have gathered increasing attention to address some of the heavy power demands of modern technology. In redox capacitors, charge is stored chemically via oxidation/reduction processes in the active materials like ... Per saperne di più
The paper attempts to give a contribution to the dynamic analysis of musical instruments. A multidisciplinary approach oriented to the study of mechanical, structural, vibratory and acoustical phenomena related to stringed instruments is discussed. The case study focused in this paper ...
