Abstract An increasing demand for bioelectronics that interface with living systems has driven the development of materials to resolve mismatches between electronic devices and biological tissues. So far, a variety of different polymers have been use

In this paper, a multi-objective optimisation for the initial design of crashworthy composite structures is proposed. The focus is on the optimisation model with its minimisation of inhomogeneous deformation capability. It promotes homogeneous contri

Faser-Metall-Laminate als Kombination metallischer Werkstoffe und Faserkunststoffverbunde sind aktuell Inhalt vieler Forschungsprojekte. Durch eine geschickte Kombination der beiden Werkstoffklassen erhofft man sich, deren inharente Schwachen zu komp

In the presented study the response of a carbon-glass composite/steel/(elastomer) multi-material structure to low-velocity impact was investigated experimentally. Two different steel layer thicknesses, 0.125 mm and 0.25 mm, as well as the addition of

The design of thin-walled structures still relies on empirical guidelines like the NASA SP-8007 for cylinders up till now. This lower-bound guideline does not include important mechanical properties of laminated composite materials, such as the stack

This paper is focused on a method for calculating the optimal drape origin on arbitrary surfaces considering a minimal shear-deformation of the applied fiber-reinforced material. The presented method is based on the mesh from a triangulated surface a

The Bi-directional Evolutionary Structural Optimization scheme (BESO) is a well tested method for a wide range of topology optimization problems. In this paper a heuristic selection scheme for orthotropic materials is implemented in a 2D BESO algorit
