Paper "A new generalized Drucker–Prager flow rule for concrete under compression" published

Submitted by Jinqing Bao on
research

This paper is on my work at Singapore. I think this paper has the following contributions

(1) A concise flow rule is proposed for concrete, every item in the flow rule has clear physical meaning

(2) Let us know that for any material, the flow rule can be simple, and we don't have to pay attention to the potential funcion.

(3) When we propose a plastity constitutive law, we don't have to rely on commercial software like 

Abaqus any more, as a numreical calibration method is introduced.

Deep Rolling simulation in ABAQUS

Submitted by farajzare on
software

Hi all

I want to simulate the deep rolling process(as seen as in attachment)

in this model I defined 2 steps,at first, the rigid ball create a pressure to cylinder to create residual stress and at the second step the ball begins displacement with

a low speed in direction of cylinder longitude to create surface overlap, while the cylinder is rotating in both steps.

in this model I have used the explicit solver but it takes too much time and elements convergence cannot be accomplished.

how can i reduce the time of my solution?

Scanning AC nanocalorimetry study of Zr/B reactive multilayers

ultra high temperature ceramic

The reaction of Zr/B multilayers with a 50 nm modulation period has been studied using scanning AC nanocalorimetry at a heating rate of approximately 1,000 K/s. We describe a data reduction algorithm to determine the rate of heat released from the multilayer. Two different exothermic peaks are identified in the nanocalorimetry signal: a shallow peak at low temperature (200 - 650°C) and a sharp peak at elevated temperature (650 - 800°C).
