Detailed Description

Prescribes macroscopic displacement gradient, reinforcement slip field and slip gradient on the reinforced concrete RVE using Dirichlet boundary conditions, cf. Sciegaj, A., Larsson, F., Lundgren, K., Nilenius, F., & Runesson, K. (2019). A multiscale model for reinforced concrete with macroscopic variation of reinforcement slip. Computational Mechanics, 63(2), 139–158. https://doi.org/10.1007/s00466-018-1588-3 Macroscopic slip and slip gradient fields are optional (see PrescribedDispSlipHomogenization). If not specified, this BC will prescribe only the displacement gradient, i.e., it will work the same was as a PrescribedGradient bc. Works with 2D RVEs comprising solid elements (concrete), reinforcement (beam/truss elements) and interface elements in between. Used in multiscale analyses of reinforced concrete structures. Currently, only orthogonal reinforcement in X and Y direction is supported.

This BC can be applied to the set of:

nodes lying at the concrete boundary. In order to prescribe macroscopic displacement gradient on both concrete and steel, the node set this BC is applied to must include the end (boundary) nodes of the reinforcement bars as well. conboundset should contain only elementboundaries of concrete elements, e.g. PrescribedDispSlipBCDirichletRC 1 loadTimeFunction 1 dofs 2 1 2 ccoord 3 0.0 0.0 0.0 dispGrad 2 2 {0 0; 0 0} set 5 conboundset 6 where set 5 contains all boundary nodes (concrete+steel) and set 6 contains boundary of concrete elements
elementboundaries of concrete elements. In this case displacement gradient is not prescribed on the reinforcement. PrescribedDispSlipBCDirichletRC 1 loadTimeFunction 1 dofs 2 1 2 ccoord 3 0.0 0.0 0.0 dispGrad 2 2 {0 0; 0 0} set 5 conboundset 5 where set 5 contains boundary of concrete elements

If the macroscopic slip/slip gradient field is to be prescribed onto the RVE, the optional node sets reinfxbound and reinfybound must be specified. These node sets contain the boundary nodes of the horizontal and vertical reinforcement, respectively.
