A Review on the Mechanical Modeling of Composite Manufacturing Processes.

Arch Comput Methods Eng 2017 20;24(2):365-395. Epub 2016 Jan 20.

4Department of Mechanical Engineering, Technical University of Denmark, 2800 Lyngby, Denmark.

The increased usage of fiber reinforced polymer composites in load bearing applications requires a detailed understanding of the process induced residual stresses and their effect on the shape distortions. This is utmost necessary in order to have more reliable composite manufacturing since the residual stresses alter the internal stress level of the composite part during the service life and the residual shape distortions may lead to not meeting the desired geometrical tolerances. The occurrence of residual stresses during the manufacturing process inherently contains diverse interactions between the involved physical phenomena mainly related to material flow, heat transfer and polymerization or crystallization.

Numerical Simulation of Fracking in Shale Rocks: Current State and Future Approaches.

Arch Comput Methods Eng 2017 29;24(2):281-317. Epub 2016 Jan 29.

2Science Labs, Department of Earth Sciences, Durham University, Durham, DH1 3LE UK.

Extracting gas from shale rocks is one of the current engineering challenges but offers the prospect of cheap gas. Part of the development of an effective engineering solution for shale gas extraction in the future will be the availability of reliable and efficient methods of modelling the development of a fracture system, and the use of these models to guide operators in locating, drilling and pressurising wells. Numerous research papers have been dedicated to this problem, but the information is still incomplete, since a number of simplifications have been adopted such as the assumption of shale as an isotropic material.
