Aggregate stability is a key factor in the evaluation of soil structure and erosion resistance, which largely influenced by electric field particle interaction. However, there are few studies on how different organic inorganic conditioners change surface interaction force reclaimed to improve aggregate stability. Therefore, five-year experiment was conducted quantitatively study effects FeSO4 (...

The energy absorbing capability is one of the most important aspects of crushing behavior of a structure subjected to axial impact. In this paper, a simple practical method is introduced to enhance the crushing behavior of this kind of structure. The axial impact of metallic energy absorbing thin-walled tubes with special shaped cross-section is simulated using LS-DYNA software. The effect of c...

Particle breakage in soils is a well-recognised behaviour. Conventional methods for quantifying the process rely on calculating area between particle size distribution (PSD) curves produced before and after crushing. A key aspect of understanding across different size/sieve fractions. Grading entropy coordinates allow representation any PSD to be shown as single point Cartesian plane are able t...

Collision of ships with oil tankers poses, next to grounding, one of the most serious environmental threats at sea. In many previous analyses of the collision problem, the bow of the impacting ship was considered rigid. The objective of the present research is to include the finite strength of the bow in the overall collision simulation. The emphasis will be placed on typical raked shapes becau...

A finite element methodology has been developed for predicting the behaviour of honeycomb structures. Dynamic analysis of hexagonal aluminium honeycomb structures is carried out using PAM-CRASH, an explicit FE analysis code, and the result are verified against experimental data. Relationship between the crushing behaviour of honeycomb and simulation parameters has been established. The simulati...
