Pretreatment for pre-coated metal sheets.

Deformation Limits of Polymer Coated Metal Sheets

Methods A Finite Element Method (FEM) model is used to simulate industrial forming processes such as bending and deepdrawing. The model consists of multiple polymer and metal layers. The simulations are performed using the FEM programMARC, which is coupled to an external program. The coupling is required for the meshing of the model and other features. Results Bending and deep-draw simulations ...

The Acoustoelastic Effect: EMAT Excitation and Reception of Lamb Waves in Pre-Stressed Metal Sheets

The acoustoelastic effect relates the change in the speed of an acoustic wave travelling in a solid, to the pre-stress of the propagation medium. In this work the possibility of assessing nondestructively the stress status in metal sheets, by using the acoustoelastic effect, is investigated. As the effect turns out to be very small for practical values of applied stress, the proposed technique ...

The Preparation, Powder Coating and Curing of Pre-cut Metal Sheets

Pre-combustion CO2 capture by transition metal ions embedded in phthalocyanine sheets.

Transition metal (TM) embedded two-dimensional phthalocyanine (Pc) sheets have been recently synthesized in experiments [M. Abel, S. Clair, O. Ourdjini, M. Mossoyan, and L. Porte, J. Am. Chem. Soc. 133, 1203 (2010)], where the transition metal ions are uniformly distributed in porous structures, providing the possibility of capturing gas molecules. Using first principles and grand canonical Mon...

Fracture of Metal Coated Elastomers

Polydimethyldisiloxane (PDMS) substrates were coated with thin layers of gold varying in thickness between 40 nm and 160 nm. Arrays of parallel cracks formed when a tensile strain was applied to the coated system, with the spacing between the cracks being approximately inversely proportional to the strain. When the crack profiles were examined, it was noted that the cracks extended deep into th...
