The energy-momentum tensor (EMT) and corresponding gravitational form factors(GFFs) provide us information about the internal structure like spin, mass andspatial densities of the proton. The Druck gravitational (D-term) form factoris related to the mechanical stability of the proton and gives informationabout the spatial distributions of the forces inside the hadron. In this work,we study the GFFs in the framework of the light-front quark diquark model. Themodel has been successful to derive various properties of protons. Weinvestigate the three-dimensional spatial distributions of proton as an Abelimage of two-dimensional distributions in this model[1]. We explicitly show theglobal and local stability conditions which are satisfied by both 2D and 3Ddistributions in our model. We compare our results with the chiral quarksoliton model, JLab and lattice data.
