Composite Patch Repair for Underwater Aluminum Structures

Composite Repair of Timber Structures

Bonded composite repair structures multiple site damage analysis

Purpose – The purpose of this work is to describe the effects of the length of cracks and the patch size on the stress intensity factors in a bonded composite repair structure containing multiple site damage. Design/methodology/approach – Finite element method was applied to simulate a bonded repair of a cracked aluminum plate with multiple site damage. A two-dimensional three-layer technique w...

Simulation of Foaming and Deformation for Composite Aluminum Foams

In this study, at the first stage, the rupture criterion of bubbles wall in Aluminum metal foam liquid was investigated by using Lattice Boltzmann. The two phases modeling were accomplished by using a modified Shan-Chen model. This model was run for several bubbles in A356+3wt.%SiC melt system. Then, bubbles morphologies (virtual metallographic) for A356+3wt.%SiC foams were simulated. Results s...

From Patch to Repair

The anatomy of the urethral sphincter in both sexes has not been undisputed since it was first described more than 160 years ago. Although 18th and 19th century explanations of the urethral sphincter were most precise and thorough, contemporary textbooks lack details and include inaccuracies and ambiguous statements or illustrations [1,2]. There is currently a need to examine how much we know, ...

Modeling Underwater Structures

Deliberate exploitation of natural resources and excessive use of environmentally abhorrent materials have resulted in environmental disruptions threatening the life support systems. A human centric approach of development has already damaged nature to a large extent. This has attracted the attention of environmental specialists and policy makers. It has also led to discussions at various natio...
