Influence of bolted-joint slippage on the response of transmission towers subjected to frost-heave

Rajapakse, R.K.N.D.; Gadala , Mohamed , S; (SAGE Journals, 2009-02)

Slippage of bolted joints is an important factor in the behavior of transmission towers. Field inspections of towers located in the northern regions of Canada show substantial frost-heave induced displacements. The ...
A temperature-dependent two-step domain-switching model for ferroelectric materials

Senousy, M.S.; Rajapakse, R.K.N.D.; Gadala, Mohamed S. (Science Direct, 2009-10)

Piezoelectric stack actuators are promising candidates for use in fuel injection technology. Experimental results for stack actuators have shown that a significant amount of heat is generated when they are driven under ...
