Roll up your sleeves

When you push up your sleeves, wrinkles form, which eventually evolve into ridges (pictured). As familiar as you may be with this phenomenon, have you ever thought about its underlying mechanism? It involves the complex nonlinear mechanical behaviour of large deformations and surface instabilities, which in turn give rise to a sophisticated morphological evolution. And now, Yifan Yang and co-workers have revealed a hitherto unknown post-buckling behaviour that involves multiple bifurcation transitions (Phys. Rev.

Postdoctoral vacancy (3 years) on high-frequency vibration techniques for non-destructive inspection of 3D printed metal parts

 

The use of 3D printed metal structures is taking a very fast ramp-up in industry. General Electric has demonstrated the possibility of printing titanium fuel injectors for their LEAP engine, EADS has printed a nacelle hinge bracket for the Airbus A320, Boeing is printing plastic inlet ducts for high-altitude aircrafts, hip implants and other prosthetics are exploiting the design freedom of additive manufacturing (AM),...

PhD vacancy (4 years) on fatigue testing of composites with advanced instrumentation

Composites are used more and more as structural components in aerospace industry, automotive sector, wind energy applications,… As a consequence, the loads on those composite components are much higher than for secondary components, and can lead to fatigue damage in the composite part. Moreover, the fatigue behaviour of fibre-reinforced composites is much more complex than that of metals, because of the many different fibre/polymer combinations, the heterogeneous nature of the composite, the anisotropic behaviour of the composite and the multitude of damage mechanisms.

Modified multiplicative decomposition model for growth: Beyond the initial stress-free state

The multiplicative decomposition model is widely employed for predicting residual stresses and morphologies of biological tissues due to growth. However, it relies on the assumption that the tissue is initially in a stress-free state, which conflicts with the observations that any growth state of a biological tissue is under a significant level of residual stresses that helps to maintain its ideal mechanical conditions.

How to combine VUMAT an VUEOS in Abaqus

Hi,

I have written a VUMAT for Johnson Cook Model. I would like to use subroutine VUEOS to define linear Mie-Gruneisen equation of state. The USUP type VUEOS subroutine can be found at Abaqus Documentation.

However, I am not able to figure out how to combine the two subroutines. What needs to be called from VUEOS into VUMAT?

Thanks,

Rohan
