Objective: To evaluate the effects of varying numbers of layers of plaster of Paris bandages on the mechanical properties of specimens used on the construction of orthopedic splints. Methods: Rectangular plate-shaped and cylinder-shaped specimens were constructed and assigned to two groups simulating plaster slabs and cast and further divided into six subgroups according to the number of layers...

The aim of this study was to obtain a predictive model able to perform an early detection of central segregation severity in continuous cast steel slabs. Segregation in steel cast products is an internal defect that can be very harmful when slabs are rolled in heavy plate mills. In this research work, the central segregation was studied with success using the data mining methodology based on mu...

Electromagnetic stirring is widely used in continuous casting of steel as a means to improve homogeneity of cast slabs. Industrial experience has shown that stirrer design and operating conditions have a strong influence on the metallurgical quality of the cast slab. This paper examines the effect of the stirrer current and field frequency on the flow in horizontal EMS of steel slabs. A threedi...

The ballistic perforation resistance of 50 mm thick concrete slabs impacted by 20 diameter ogive-nose steel projectiles is investigated experimentally and numerically. Three commercially produced concretes with nominal unconfined compressive strengths 35, 75 110 MPa were used to cast material test specimens slabs. After curing, impact tests carried out determine the limit curve velocity for eac...

The main objective of this project was to investigate the behavior and the damaging effects of hot tear segregations in the continuously cast steel blooms on the final product quality. To achieve this aim, plant data from three different types of steels were used. Investigations using the scanning electron microscope (SEM) equipped with energy dispersive x-ray spectroscopy (EDS) probe and metal...
