Kenneth Langstreth Johnson. 19 March 1925 — 21 September 2015

I strongly recommend reading these two papers about the recent loss of Ken L Johnson, FRS, Timoshenko Medallist, Gold Tribology Medal, who died the day of my 45th birthday, exactly twice as old.

ABAQUS - the influence of changing kinematic and cycling hardening parameters

Choose a channel featured in the header of iMechanica: 

Hello,

 

I have recently done a simple hourglass model to check the influence of hardening parameters in Abaqus. The reason was the effects of the parameters' change in bigger models were a bit surprising, therefore I needed to investigate the reason using some simpler model. Please see file 1.

 

After performing tension/compression cycles I got results as shown in files 2, 3, 4 and 5. Please note that only the hardening parameter in the description changes, the other three stays the same for each series.

Obituary for prof. Paul Paris the inventor of the fatigue crack propagation "Paris' law"

I do not think in Imechanica there has been an obituary for Paul Paris, whose work in fatigue crack propagation is extraordinary and one of the few important and lasting contributions ----- today our aircrafts, both civil and military, all rely on "damage tolerance", which is based on Paris' law.   Paris' law, as every great innovations, was published in 1961 only after rejection by three of the leading journals in the fracture mechanics field.  It bears the name of "law" although of course it is not like Newton's law.  It is a power law, based perhaps on what Barenblatt calls "incomplete"

2018 Thomas K. Caughey Dynamics Award – Professor Firdaus Udwadia

The Executive Committee of the ASME Applied Mechanics Division is pleased to announce and congratulate Professor Firdaus Udwadia, Professor of Civil Engineering, Aerospace & Mechanical Engineering, University of Southern California, as the recipient of the 2018 Thomas K. Caughey Dynamics Award.

2018 Thomas J.R. Hughes Young Investigator Awards – jointly to Professor Dennis Kochmann and Professor Liping Liu

The Executive Committee of the ASME Applied Mechanics Division is pleased to announce and congratulate both Professor Dennis Kochmann, Professor of Mechanics and Materials, ETH Zürich, and Professor Liping Liu, Associate Professor of Mechanical & Aerospace Engineering, Rutgers University, as the joint recipients of the 2018 Thomas J. R.

Half Space Problems

Hi Dear

I have a question about half space problems.

When I want to solve a half space problem by utilize a numerical method such as FEM how I should consider the boundary counditions at the infinite bound??

when I want to solve with a analytical method I know it but What I should do for FEM at infinite bound??
