EFFECT OF TRANSIENT THERMAL GRADIENT ON STRESSES IN COMPOSITE BRIDGES
Proceedings of International Structural Engineering and Construction, 2019 Composite steel-concrete bridges experience higher thermally induced stresses than their concrete and steel cousins. These thermal stresses which can result from support restraints, debris accumulating in expansion joints, or from non-uniform thermal gradients, can lead to significant damage in the concrete deck.

Stress Gradient Plasticity: Concept and Applications [PDF]
, 2014 The effect of a linear applied shear stress gradient on the yield stress of a dislocation pileup is investigated analyti- cally using the continuum theory of dislocation pileups. The solution agrees well with numerical discrete dislocation simulations of
