Simulation of Thermo-Mechanical Strain in Extruded Polymeric Absorbers for Solar Thermal Collectors

E. Klimm [1], C. M. Yandiola [1], A. Piekarczyk [1], K.-A. Weiss [1],
[1] Fraunhofer Institute for Solar Energy Systems, Freiburg, Germany

Solar thermal energy, compared to fossil fuels, is an environmentally friendly alternative for heating and hot water production. Recent research suggests that polymeric materials can be a cost-saving and environmentally friendly alternative to the common metals used in solar thermal ... Read More

Simulation of Chemo-Thermomechanical Aging of Rubber

B. Musil [1], M. Johlitz [1],
[1] Universität der Bundeswehr München, Institute of Mechanics, Neubiberg, Germany

This work shows the finite element implementation of a constitutive model which can represent the chemo-thermomechanical aging of rubber. This approach considers the nonlinear thermo-viscoelastic behavior of rubber, is formulated for finite deformations in the continuum mechanical ... Read More

Modeling of Viscoelastic Phenomena in Concrete Structures

A. Pomarico [1], G. Roselli [1], D. Caltabiano [2],
[1] STMicroelectronics, Lecce, Italy
[2] STMicroelectronics, Agrate, Italy

A growing demand is recently emerging of sensors to be integrated in the concrete in order to measure some critical parameters, such as humidity and temperature and the internal pressure of the material. For example, by monitoring the pressure in various strategic points of the structure ... Read More

2D Modeling of Elastic Wave Propagation in Solids Containing Closed Cracks

S. Delrue [1], V. Aleshin [2], O. Bou Matar [2], K. Van Den Abeele [1],

[2] Institute of Electronics, Microelectronics and Nanotechnologies, Lille, France

Within the field of Non Destructive Testing (NDT) of materials, nonlinear ultrasonic techniques are becoming increasingly popular, since they provide extreme sensitivity in detecting the presence of incipient damage. However, the next step forward would be to fully characterize the ... Read More

The Spherical Design Algorithm in the Numerical Simulation of Fiber-Reinforced Biological Tissues

M. Carfagna [1], A. Grillo [1],
[1] Dipartimento di Scienze Matematiche, Politecnico di Torino, Italy

The numerical results of the unconfined compression test on a sample of Articular Cartilage (AC) are discussed. AC is modelled as a load-bearing, deformable, fiber-reinforced material filled with an interstitial fluid and comprising statistically oriented collagen fibers, chondrocytes, ... Read More

基频最大的经纬仪基座的拓扑优化
