Does internal heat transfer attribute work with VUMAT subroutine?
I am running J-C plasticity VUMAT subroutine and trying to club inbuilt heat transfer attributes for temperature update, but it's not working. I would appreciate if someone can advise me if there any way to club inbuilt heat transfer with VUMAT or I have to write separate subroutine?
Thanks & Regards,
Abhishek
Soft mobile robots driven by foldable dielectric elastomer actuators
A cantilever beam with elastic hinge pulled antagonistically by two dielectric elastomer (DE) membranes in tension forms a foldable actuator if one DE membrane is subject to a voltage and releases part of tension. Simply placing parallel rigid bars on the prestressed DE membranes results in enhanced actuators working in pure shear state. We report design, analysis, fabrication and experiment of soft mobile robots that are moved by such foldable DE actuators.
Post-Doc position within the International Research Training Group "Integrated Engineering of continuous-discontinuous long fiber reinforced polymer structures” (DFG GRK 2078)
The international research training group "Integrated Engineering of continuous-discontinuous long fiber reinforced polymer structures” offers one post-doc position at Karlsruhe Institute of Technology (KIT). Discontinuous long fiber reinforced polymer structures with local continuous fiber reinforcements represent an important class of lightweight materials. This class of materials has a significant potential for energy savings due to the high specific stiffness and strength as well as the variety of design options in diverse technical applications, e.g., in vehicle construction.

Abstract:
Defining perioidc BC for 1 element elastic model for Biaxial pull in ABAQUS
For simplicity in understanding Perioidic BC in ABAQUS, I am trying to implement in a single element elastic model.
Material is elastic. There are two reference points defined Refpoint 1 for x-direction pull and Refpoint 2 for y-direction pull. Please find the attached picture for clarity in the model.
I have defined the equations for PBC in ABAQUS as below:
x1-x2+Refpoint1=0
y1-y2+Refpoint1=0
x3-x4+Refpoint1=0
y3-y4+Refpoint1=0
x2-x3+Refpoint2=0
y2-y3+Refpoint2=0
Elastic Microplane Formulation for Transversely Isotropic Materials
Our recent work investigates the extension of the microplane formulation to the description of transversely isotropic materials such as shale rock, foams, unidirectional composites, and ceramics. Two possible approaches are considered: 1) the spectral decomposition of the stiffness tensor to define the microplane constitutive laws in terms of energetically orthogonal eigenstrains and eigenstresses; and 2) the definition of orientation-dependent microplane elastic moduli.
Microstructure modeling of random composites with cylindrical inclusions having high volume fraction and broad aspect ratio distribution
We proposed a computational methodology for generating microstructure models of random composites with cylindrical or sphero-cylindrical inclusions having high volume fraction and broad aspect ratio distribution. The proposed methodology couples the random sequential adsorption (RSA) algorithm and dynamic finite element (FE) simulations. It uses RSA to generate sparse inclusion assemblies of low volume fraction and subsequently utilizes dynamic FE simulation for inclusion packing to achieve high volume fractions.
