Strain values transformed in a rotated x'y'-Cartesian coordinate system with ABAQUS

Dear All,

I'm trying to get strains in some specific points (along a path) from the xy-Cartesian coordinate system to a local x'y'-Cartesian coordinate system rotated through an angle (theta) which means transform the strains (Ex,Ey) to (Ex',Ey') as described in the attached figure, something I usually do manually with Mohr's circle and I wonder if I can do it directly with Abaqus ?

Thank you in advance !

Regards.

Mohammed.

The strength and dislocation microstructure evolution in superalloy microcrystals

In this work, the evolution of the dislocations microstructure in single crystal two-phase superalloy microcrystals under monotonic loading has been studied using the three-dimensional discrete dislocation dynamics (DDD) method. The DDD framework has been extended to properly handle the collective behavior of dislocations and their interactions with large collections of arbitrary shaped precipitates. Few constraints are imposed on the initial distribution of the dislocations or the precipitates, and the extended DDD framework can support experimentally-obtained precipitate geometries.

Textile Composite Property Calculator in the Cloud

I hope this information will be helpful for some researchers. We recently integrated TexGen with SwiftComp, called TexGen4SC, to provide a very easy app to compute thermoelastic properties for textile composites for all the types of woven microstructures which can be generated by TexGen. This tool can achieve RVE analysis accuracy with a very small fraction of its computing time. This tool can respect the finite thickness of a woven fabric. It can be freely launched on any device (smart phones, ipads, etc) connected to Internet.

Exact solution of Qian equation of slender toroidal shells

In 1979 Qian Weichang studied the slender toroidal shell systematically and derived a called Qian’s equation, then obtained a series solution with the expression of continued fractions. But Qian did not mention if the series solution can be converted to a well-known special functions. In this paper, a linear transformation has been introduced, which will transfer the equation into a Mathieu equation, whose solution can be expressed in terms of Mathieu functions. This study has revealed a intrinsic relationship between the Qian’s solution and the Mathieu solutions.

Dimensional analysis and applications (invited article)

The paper gives a systematical introduction on dimensional analysis (DA), and proposes a six-steps on how to use the dimensional analysis, the universality of the DA will be shown by some typical examples, such as, point blast, pipe flow and a small sphere moving through a viscous fluid.

A review of predictive nonlinear theories for multiscale modeling of heterogeneous materials

Since the beginning of the industrial age, material performance and design have been in the midst of innovation of many disruptive technologies. Today’s electronics, space, medical, transportation, and other industries are enriched by development, design and deployment of composite, heterogeneous and multifunctional materials. As a result, materials innovation is now considerably outpaced by other aspects from component design to product cycle. In this article, we review predictive nonlinear theories for multiscale modeling of heterogeneous materials.
