    Abstract: Crankshaft is large volume production component with a complex geometry in internal combustion Engine (ICE), which converts the reciprocating displacement of the piston into a rotary motion of the crank. An effort was done in this paper to improve fatigue life for single cylinder engine crankshaft with geometric optimization. The modeling of the or... Show More

    Abstract: Failure investigation was carried out on a refinery steam boiler had a history of good performance with few leakages and damages that were successfully weld repaired. The steam boiler tubes were observed to have developed several perforations / punctures on numerous furnace chamber tubes, twenty two years after commissioning. In the course of the i... Show More

    Abstract: Calcined clay pozzolan, the major mineral admixture used in Ghana to partially substitute ordinary Portland cement has gained massive recognition in the local construction industry because of its technical advantages and affordability. The most prominent undesirable property associated with the use of calcined clay pozzolans is slow setting and str... Show More
