Advantages Versus Disadvantages

There are numerous fireproofing materials available on the marketplace and the selection of the material involved is based on the application and advantages versus disadvantages of each over an economic factor. Usually no single material is ideally suited for a particular application, and an evaluation of the cost, durability, weatherability, and combination of factors is necessary. 

Polyolefins—specifically, polyalpha olefins—are made from polymerizing alpha olefins where the double bond is located at the alpha carbon atom. Figure 7.7 shows 1-hexene. The double bond is located between the first and second carbon atoms and, as a result, they have flexible alkyl branching groups on every opposite carbon in the chain. The flexibility due to the different configurations makes crystallization difficult. Because polyalpha olefins are able to remain flexible at lower temperatures, they are ideal as a synthetic motor oil. Some advantages versus disadvantages of synthetics are shown in Table 7.4...

EN can be administered through four routes, which have different indications, tube placement options, advantages, and disadvantages (Table 58-1). The choice depends on the anticipated duration of use and the feeding site (i.e., stomach versus small bowel). 

Selection of the material model is another important factor to be considered. Some programs allow the user to specify plastic moment-rotation curves for beam elements. However, the more rigorous and most widely available method of defining nonlinear material properties is to specify the stress versus strain data, Plastic behavior is approximated at the section level in the former method whereas, the latter method tracks plastic behavior at the individual integration points (fibers) through the thickness of the member. Each method has its advantages and disadvantages.
