UMAT and VUMAT Subroutines for GTN Model

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. 

 

Regards

Relation between plasticity and damage in studying the frictional behaviour between two composite laminates.

Hi all, 

     I want to model mode II composite delamination incorporating frictional effects. I found papers by Alfano and Sacco (2006) and few others also. My question is that to model such a situation are :

1) should I incorporate plasticity or damage analysis or both? What is the rite approach? 

2) In each of these cases, do I need to have a plastic yield function and damage surface ??

PhD with 5 Years of R&D and Industrial Experience, Actively Seeking a Job/Research Position in Acoustics and Vibration/Vibro-acoustics/Structural Dynamics/Noise and Vibration

I am an experienced professional in structure borne sound, structural and machinery dynamics, vibro-acoustics, and now actively looking for a career opportunity in R&Ds or in Industries. Ph.D. in acoustics & vibration, around 5 years of work experience in R&Ds and Industries, published articles in reputed international Journals and Conferences with modelling, simulation, testing and analysis experience backed by relevant course-works. In achieving this, I have shown myself to be self-motivated, committed and determined in arriving at my goals.

PhD studentship in Mechanics of Materials - Draping of non-crimp fabrics

The aim of the PhD is to develop a micromechanical model for forming of non-crimp fabrics (NCFs), and use this to optimise the pre-forming process for manufacture of complex shapes. The work will include both experimental work and finite element modelling. The work will benefit from close links with industrial partners Formax (manufacturer of NCFs), Simulia (developers of Abaqus forming simulation tools) and Jaguar Land Rover.

Mechanical Self-Assembly of a Strain-Engineered Flexible Layer: Wrinkling, Rolling, and Twisting

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.
