Finite element analysis of concrete cracking at early age
Aurich, Mauren,Filho, Americo Campos,Bittencourt, Tulio Nogueira,Shah, Surendra P. Techno-Press 2011 Structural Engineering and Mechanics, An Int'l Jou Vol.37 No.5
The study of the early age concrete properties is becoming more important, as the thermal effects and the shrinkage, even in the first hours, could generate cracks, increasing the permeability of the structure and being able to induce problems of durability and functionality in the same ones. The detailed study of the stresses development during the construction process can be decisive to keep low the cracking levels. In this work a computational model, based on the finite element method, was implemented to simulate the early age concrete behavior and, specially, the evaluation of the cracking risk. The finite element analysis encloses the computational modeling of the following phenomena: chemical, thermal, moisture diffusion and mechanical which occur at the first days after the concrete cast. The developed software results were compared with experimental values found in the literature, demonstrating an excellent approach for all the implemented analysis.

Sustainability in Ultra precision and Micro machining: A Review
Frank Schneider,Jayanti Das,Benjamin Kirsch,Barbara Linke,Jan C. Aurich 한국정밀공학회 2019 International Journal of Precision Engineering and Vol.6 No.3
Ultra precision and micro machining processes become more and more important. This can be led back to the development of functionalized surfaces and parts and the mass production of smaller products e.g. lenses for personal devices. With increasing application and distribution, the importance of sustainability in these processes also increases. In this paper, an overview of ultra precision and micro machining in a system approach is given and the most decisive input parameters are elaborated. Included are general findings and current issues of process design with regard to the economic, environmental and social dimension of sustainability. Finally, it is discussed how the sustainability of ultra precision and micro machining can be increased and for which class of products certain strategies are recommended.
