An explicit 3D Finite Element (FE) model was developed in the LS-Dyna code to simulate laser shock paint stripping on aircraft aluminum substrates. The main objective of is explain physical mechanisms process terms wave propagation, stress and strain evolution shape size evaluate effects material parameters pattern. To behavior aluminum, Johnson–Cook plasticity Gruneisen equation state were app...

A new simple experimental approach is proposed for in situ mechanistic studies of the underpaint stability metal/oxide/polymer interface under immersion. It allows an intelligent screening and fast ranking conversion coatings on Zn alloys designed further application organic coatings. The based a electrochemical aging protocol to samples preliminary coated with model epoxy-polymer. latter enoug...

Coatings are important instruments in inhibiting the corrosion rate. Field facts various Indonesian shipping industries show that choice of organic materials as coating for ship paint uses epoxy, vinyl and polyurethane. Therefore an experimental study is needed on adhesion ability a armor with these three types materials. The preparation steel specimens type ASTM A36 carried out by blasting, vi...

Isocyanate-free cathodic ED coatings. Most of the resins used in the cathodic electrodeposition (CED) coatings are made from modified epoxy resin and blocked polyisocyanate in which the crosslinking is achieved by polyurethane and polyurea formation. A resin system has been developed that is isocyanate free and avoids not only the toxicity aspect, but also, to a great extent, the weight loss of...

In this study, the authors use the finite element method to model and analyse a cylindrical copper shelled SLA electrode for EDM operations, which is investigated experimentally in literature. A uniform silver paint thickness and copper shell thickness is assumed around the SLA epoxy core. In the experiment, 2-D analysis was used due to the axissymmetric shape, and steady state and transient di...
