Investigation of effect of polyurea on response of steel

Investigation of effect of polyurea on response of steel

Jun 01, 2010· In a recent study, Amini et al. (2010a) employed a reverse impact experimental technique to investigate the effect of polyurea on the impulsive response of steel plates. Using direct penetration tests, Mock and Balizer (2005) report that a polyurea layer cast onto the back face of a steel plate can change the response of the plate from full Investigation of effect of polyurea on response of steel Investigation of effect of polyurea on response of steel plates to impulsive loads in direct pressure pulse experiments Article in Mechanics of Materials 42(6):628 639 · June 2010 with 180 ReadsInvestigation of effect of polyurea on response of steel On the other hand, when polyurea is placed on the front face (load receiving side), it will magnify the initial shock effect and promote failure. These experimental results are paralleled by numerical simulations of the entire experiment, employing physics based models for the DH 36 steel and polyurea (Amini et al., 2010b.

Investigations on Aging Behavior and Mechanism of Polyurea

In this investigation, the aging behaviors of polyurea coating exposed to marine atmosphere for 150 days were studied and the mechanism was analyzed. The influences on surface and mechanical properties, surface morphology, thermal stability behavior, as well as chemical changes evolution of the coating were investigated.
