Structural and Multidisciplinary Optimization
Traditionally, the design of building envelope components is primarily focused on meeting technical requirements rather than finding optimal design solutions. New components are typically generated using numerical models validated by experiments, and the general methodology mainly consists of extensive numerical parametric studies. Since the basic ...

Due to restrictions imposed by legal requirements, automotive manufacturers are forced to reduce the pollutants emission of new models. A promising approach is the reduction of the vehicle weight, whereby the body in white offers great potential. This weight reduction is realized by new car body constructions, which contain the increasing usage of ...

Intrinsic hybrids present a new approach to join metal and CFRP, to produce multi-material components which utilise the particular advantages of the involved materials. Due to the intrinsic hybridisation, no additional process steps are required and the total weight of the component can be reduced. The present special issue was initiated within the...

The implementation of lightweight materials such as modern wrought aluminium and casting alloys enables a significant reduction of the vehicle’s total mass. The extended use of lightweight aluminium castings and extrusions offers considerable potential for weight reduction. The cost-effective joining of these aluminium structures is challenging the...

The main objective of this paper is to introduce a novel method to develop a multi-material body-in-white concept with composite material or hybrid material system. A new method based on the work of Durst (2008) is presented, which works basically in three steps. In the first step, the anisotropy of the components is analyzed to pre-evaluate the po...

Due to the fact that car attributes like the dynamic drive ability, CO2 emissions and efficiency are factors which are massively influenced by the total vehicle mass; lightweight becomes a key issue in modern car body design. Nowadays, most cost-effective lightweight solutions can be achieved by multi-material design. This restricts conventional th...

Structural and Multidisciplinary Optimization
In this paper an ordered multi-material SIMP (solid isotropic material with penalization) interpolation is proposed to solve multi-material topology optimization problems without introducing any new variables. Power functions with scaling and translation coefficients are introduced to interpolate the elastic modulus and the cost properties for mult...

Structural and Multidisciplinary Optimization
Finding the optimum distribution of material phases in a multi-material structure is a frequent and important problem in structural engineering which involves topology optimization. The Bi-directional Evolutionary Structural Optimization (BESO) method is now a well-known topology optimization method. In this paper an improved soft-kill BESO algorit...

For the successful multi-material design of an automotive body, joining methods for dissimilar materials such as high-strength steel, aluminum alloy, and carbon fiber reinforced plastic (CFRP) are required for assembling automotive components comprising various materials. There are many methods for joining dissimilar materials, such as the use of s...
