Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique.
L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1.
C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

| Résumé : |
Cost pressure in the steel industry is high. In order to be able to produce sustainably in this market characterised by overcapacities, the focus is on increasing productivity, especially for simple steel products. This is where innovative adhesive bonding comes into play. |
| Note de contenu : |
- Adhesive bonding ensures usability
- Guarantee of product safety
- Extraction and idealisation of the load case
- Hyperelastic material modelling of short-term behaviour
- Long-term creep modelling
- Fig. 1 : Schematic diagram of the installation situation of the copper mold with solidification from the melt to the solidified semi-finished product and real implementation in the steelworks with several parallel strands for theproduction of steel billets
- Fig. 2 : Isometric view of the mold, which is elastostatically coupled to the outer plates by means of elastoc bonding - the detailed view of the steel inlet side shows the encapsulated, water-conducting cooling channels betweenthe mold and the plates
- Fig. 3 : Procedure under laboratory conditions for designing the adhesive bond for test operation in a steelworks
- Fig. 4 : Schematic representation of the standard model of viscoelasticity theory/ A/ and the expected extracted load behaviour as a function of time
- Fig. 5 : Simulation model of an idealised specimen - the simulation was used to identify the quality of the idealisation as well as the computer-based parameter identiication and implementation of idealisation in real test specimens to experimentally determine material parameters
- Fig. 6 : Schematic illustration of the developed specimen, which reproduces the effective load case in adequate approximation - the adhesive is pictured in deformed tate and attention was paid to reproduce the effective load level in an acceptable manner
- Fig. 7 : Adhesive bond with hourglassing of the mesh ; and successful elimination of the hourglassing problem and associated convergence problems by adapting the element formulation
- Fig. 8 : 200-times-magnified picture of the copper surface with adhesive residue after longterm failure - the imbricative debonding is a result of surface modification
- Fig. 9 : Maximum principal strain in the adhesive after short-term load and maximum principal strain in the adhesive after required operating time - the maximum principal strain values are element mean values |
