The previously developed analytical and numerical models for sheet bending were observed to be inaccurate for straight flanging with relatively small bending radii.
Study is conducted by firstly designing an experiment method to develop a pressure-dependent variable friction model for DP780 AHSS sheet sliding against DC53 cold-work tool.
Dorsal closure (DC) is an essential step during Drosophila development whereby a hole is sealed in the dorsal epidermis and serves as a model for cell sheet morphogenesis and wound healing.
As a consequence, in order to design a campaign of experimental tests we resorted to numerical simulations based on a novel Lagrangian, finite dimensional model for pantographic sheets.
Among these examples, a plane stress formulation is described in more detail, namely, Yld2000-2d [Barlat, F., Brem, J.C., Yoon, J.W., Dick, R.E., Choi, S.H., Chung, K., Lege, D.J., 2000. Constitutive modeling for aluminum sheet forming simulations.
In this study, a previously published continuum model for a stretched sheet was adapted to the case of a compressed sheet to understand the geometry of graphene nanoripples.
Therefore, it is well suited for the modeling of sheet metal forming and similar processes.
A general elasto-plastic model is also incorporated for the constitutive modelling of sheet forming operations with plastic anisotropy.
Appropriate calibration factors were introduced to modify the existing models for CFRP sheets.
This paper provides representative results obtained from the UniSim flow sheet model for a 300 MWe co-electrolysis plant, coupled to a high-temperature gas-cooled nuclear reactor.
