**r7.01.32** Behaviour law of reinforced concrete plates GLRC_DM
=================================================================

**Summary:**

This documentation presents the theoretical formulation and numerical integration of the law of behavior GLRC_DM, usable with DKTG modeling. It is one of the so-called "global" models used for thin structures (beams, plates and shells). Non-linear phenomena, such as plasticity or damage, are directly related to generalized deformations (extension, curvature, distortion) and generalized stresses (membrane, flexural and cutting forces). Thus, this law of behavior applies with a finite plate or shell element. Compared to a multi-layered approach, this saves CPU time as well as memory. The advantage compared to multi-layer shells is even greater, when one of the components of the plate behaves in an almost fragile manner (concrete, for example), since the global model makes it possible to avoid location problems.

The law of behavior GLRC_DM models the damage under membrane stress and under flexural stress of reinforced concrete plates, using "homogenized" parameters. This behavior model therefore represents an evolution compared to model GLRC_DAMAGE, which only treats damage under flexural stress. The structure of the damage model in GLRC_DM is similar to that of GLRC_DAMAGE and are both inspired by ENDO_ISOT_BETON. Unlike GLRC_DAMAGE, GLRC_DM does not allow the modeling of possible plasticization, which makes it less suitable for simulating extreme loads. In addition, behavior GLRC_DM is isotropic before damage: the orthotropy provided by steel reinforcement sheets is overlooked.

It is possible to consider using behavior GLRC_DM "alone" on plate modeling to represent reinforced concrete, or else only to represent concrete only by combining it then with steel reinforcement grid models, which makes it possible to represent the orthotropy and possibly the non-symmetry of the reinforcement sheets. This last choice also simplifies the configuration of this behavior.
