Stress-strain graph

Hi everyone, I am studying an example in Abaqus example problems manual (version 6.10) called "uniaxial rachetting under tension and compression". In the example there is a graph plotting axial stress-strain relationship for experiment data and simulation data. By studying the inp file I knows that the writer has ask for some outputs like RF1, RF2, RF3, S, ALPHA, ALPHAN, LE and so on in certain node and element set. However, I still can't figure out how writer use the output data from simulation to plot the axial stress-strain graph.

For the third time I am teaching the graduate course on soft active materials.  This course is called Advanced Elasticity in the Catalog of Courses.  In the last several years, I have dropped several traditional topics, and focused on thermodynamics and finite deformation.  I have added several topics where both thermodynamics and finite deformation play significant roles, such as elastomeric gels and dielectric elastomers.

question on rotation tensors

Hi,

I am doing a self-study on continuum mechanics and have the following question on rotation tensors that I would like to get answered with your help:

 

How would one come up with the rotation tensor in 3D when the axis and the angle of rotation is given. For e.g., what would be the rotation tensor in cartesian coordinates when I would like to rotate the system about n(e_1 + e_2 + e_3) by say +60 deg.

 

Thanks in advance
