There has been a terrifying ‘logic’ to the protracted civil war in Sri Lanka which came to its very sad conclusion in the third week of May 2009. It is easy to understand why people living in Colombo and the south-western part of Sri Lanka felt very relieved and even enthused by the brutal crushing of the Tamil Tiger after twenty-six years of insecurity and conflict. However, any sense of victo...
Stainless steel square honeycomb core sandwich and solid monolithic beams have been subjected to high-pressure, short-duration impulses using a shock simulation technique involving high-speed impact of Al foam projectiles. The experiments have been designed to achieve two objectives: (i) to demonstrate the benefits of sandwich construction, and (ii) to assess the fidelity of dynamic finite elem...
In this paper, the discrete element method is used to explore why differing amounts of breakage, quantified using Hardin’s relative breakage parameter (Br), are associated with the critical state line (CSL) and the normal compression line (NCL) at similar stress levels. Virtual samples initially containing more than 20,000 spherical particles were isotropically compressed to a range of confinin...
