Autor: Jan Stegmann, Moritz Baumert, Stephan Kabelac, Christian Menze, Johannes Ramme, Hans-Christian Möhring
Publikováno v: Energies, Vol 17, Iss 13, p 3189 (2024)
To improve machining processes concerning the usage of lubricants, knowledge of the thermo-mechanical and thermo-fluid interactions at the cutting zone is of great importance. This study focuses on the description of the convective heat transfer whic

Discrete material optimization of general composite shell structures
Autor: Jan Stegmann, Erik Lund
Publikováno v: International Journal for Numerical Methods in Engineering. 62:2009-2027
A novel method for doing material optimization of general composite laminate shell structures is presented and its capabilities are illustrated with three examples. The method is labelled Discrete Material Optimization (DMO) but uses gradient informa

Discrete Material Optimization of Laminated Composites - SIMP vs. Global Optimization
Autor: Jan Stegmann, Mathias Stolpe
Publikováno v: III European Conference on Computational Mechanics ISBN: 9781402049941
Technical University of Denmark Orbit
Design of laminated composites structures is becoming increasingly important as the use of composite materials steadily increases. This development is driven by the aerospace, automotive and wind turbine industries who need still lighter and stiffer/

A Newton method for solving continuous multiple material minimum compliance problems
Autor: Mathias Stolpe, Jan Stegmann
Publikováno v: Stolpe, M & Stegmann, J 2008, ' A Newton method for solving continuous multiple material minimum compliance problems ', Structural and Multidisciplinary Optimization, vol. 35, no. 2, pp. 93-106 . https://doi.org/10.1007/s00158-007-0131-5
This paper presents an implementation of an active-set line-search Newton method intended for solving large-scale instances of a class of multiple material minimum compliance problems. The problem is modeled with a convex objective function and linea
