Hi Friends,
I want to implement GTN damage model in abaqus/Explicit and Standard analysis. Is there any example tutorial or avaliable material. Please forward to me.

Can anyone know the data for the following (Johnson Cook Failure Model)
J.C. Damage Constant parameters (d1, d2, d3, d4, d5) , Transition Temperature Melting temperature and strain rate constants
There is an increasing demand for flexible, skin-attachable, and wearable strain sensors due to their various potential applications. However, achieving strain sensors with both high
sensitivity and high stretchability is still a grand challenge. Here, we propose highly sensitive and stretchable strain sensors based on the reversible microcrack formation in composite thin
films. Controllable parallel microcracks are generated in graphite thin films coated on elastomer films. Sensors made of graphite thin films with short microcracks possess high
Self-shaping of curved structures, especially those involving flexible thin layers, is attracting increasing attention because of their broad potential applications in, e.g., nanoelectromechanical andmicroelectromechanical systems, sensors, artificial skins, stretchable electronics, robotics, and drug delivery.

In this review of particularly readworthy papers in EFM, I have selected a paper about the tearing of large ductile plates, namely:

Introduction
We are trying to find out the work conjugate strain (and wryness) measures to T and M (stess and couple stress) and we know that in classical theory the conjugate strain measure is identified using the stress power, which appears in the power balance equation derived taking the inner product of the equation of motion with velocity. Please refer to the attached pdf for details.
1. Given the equations of motion of Cosserat media (Eq 1 and 2 in attached pdf) how do we extend the procedure of calculating the stress power for Cosserat media?
Thanks to the efforts of the associate editors and reviewers, JAM continues to publish very fast. Among ~800 submissions in 2015, there are only 19 papers that are still under review as of February 1, 2016. In addition, the acceptance rate continues to decline, to ~16% in 2015.
Below are references to some of our ongoing work that is published and is related to study the role of microcracking (in particular) and porosity to the thermo-mechanical response of functional ceramics. This study is relevant to understand the structural reliability of the systems such as the SOFC's (solid oxide fuel cells) and DPF's (diesel particulate filters).
