The Christian Doppler Laboratory for Micromechanics of Materials
(CDLµMW) was one of the
Christian Doppler Laboratories
established at university institutes by the
Christian Doppler Research Society.
The CDLµMW was operated jointly by the Institute of Mechanics (head: Prof. F.D. Fischer, leader of the CDLµMW) at the University of Mining and Metallurgy, Leoben, Austria, and the Institute of Lightweight Design and Structural Biomechanics (head: Prof. F.G. Rammerstorfer) at the TU Wien, Vienna, Austria.
In accordance with the rules of the Christian Doppler Research Society, the activities of the CDLµMW ceased with Dec. 31, 1997, seven years after its foundation.
The micromechanics of materials approach together with its computer oriented applications is an important tool for the understanding and prediction of the influence of the microstructure on the macroscale behavior of inhomogeneous materials, which also allows the development potential of new materials to be assessed. This holds true even for materials which cannot be produced and experimentally tested at this time. Furthermore, by using computer simulations based on micromechanical models the experimental effort in industrial materials development can be reduced.
Besides the above influences of microstructural parameters, process induced micromechanical effects (microscale residual stresses, phase transformations) are studied. The nucleation and growth of cracks as well as failure at phase boundaries are to be modelled and subsequently formulated in terms of macroscale damage descriptions. In addition, the interaction between microstresses caused by phase transitions in microscale regions and progress of the phase transition as well the global deformation behavior are investigated.
Beyond direct applications in materials development, the formulation of micromechanically based macroscopic material descriptions and their implementation into engineering software form the basis of industrial applications in the prediction of the thermomechanical behavior of components and structures made of advanced inhomogeneous materials.
