Abstract
Interaction with external gravitational field is introduced into a nonlocal quark model using the equivalence principle. This allows to define the energy-momentum tensor in flat space and evaluate its hadronic matrix element with external pions. It is found that bubble diagrams give a significant contribution to the corresponding gravitational form factors.
