Investigation of nanomechanical properties of Al/Ni and Ni/Al nanomultilayers under nanobending using molecular dynamics simulation

► The bending angle of a multilayer increases with decreasing hardness of the surface layer. ► The internal stress of a multilayer increases with increasing indentation depth and temperature. ► The required loading force and the adhesion force decrease with increasing temperature. ► The elastic recovery increases with increasing atomic bonding energy and temperature.
