Structural components, design

The viscosity function is an important factor in the assessment of the flow of plastic melts in tools for both structural component designers and processors. It describes the dependence of flow behavior on shear rate for the plastic melt (melt stress). 

Opportunities and Risks of Structural Component Design and Mold Engineering. 337... 

The risks involved in plastics processing, as in other material technologies, frequently involve poorly planned structural component designs leading to high-cost mold manufacturing and alterations. The choice of the wrong material usually means the molds have to be remade from scratch. In addition to the direct costs involved, there is the risk that a considerable amount of - costly - time will also be lost. 

The principles that apply to material selection and process engineering, i.e., those of simultaneous engineering, apply most particularly to structural component design and mold engineering. 

In this section as well, examples provide insights into the opportunities and risks involved in structural component design and mold engineering. 

The structure of complex 6 [25] can be considered as a combination of two major structural components designated as type I and type II, which are interlinked by N-H- O and N-H- -N hydrogen bonds (Figure 8.13). 

Throughout this chapter the viscoelastic behaviour of plastics has been described and it has been shown that deformations are dependent on such factors as the time under load and the temperature. Therefore, when structural components are to be designed using plastics, it must be remembered that the classical equations which are available for the design of springs, beams, plates, cylinders, etc., have all been derived under the assumptions that... 

Ref. [27] presents a thorough discussion of limits to structural components strengths, and these should be observed. Ductile design practices should be used. The maximum allowable design stress should not exceed 25% of the ultimate strength. The strength of the enclosure should exceed the vent relief pressure by at least 0.35 psi. 

Quadraxially oriented (four directional layer) glass fabric-TS vinyl ester polyester RP sheet panels with a foam core and gel coating are used. Most of the panels are 3 mm thick with molded-in rib structure supports. Body skins are bonded to the chassis with a double-stick acrylic tape developed by 3M Co. as well as mechanical fasteners. Unlike most steel designs, no B-pillar structural component between the front and rear doors is required thus providing more interior space and easy entry since doors open in opposite directions. 

CVD boron fibers which are extremely stiffand strong and are used as reinforcement in structural components in aerospace designs.

Several academic and pharmaceutical groups have conducted structure-based design and SAR studies around triclosan aiming at harvesting its potency without its biocidal component. Among the results of these efforts, CPP (24) was found to be sevenfold more tightly bound to E. coli Fabl than triclosan with an MIC value of 0.07 pg/mL, fourfold lower than that of triclosan [43]. Phenoxyphenol 25 is extremely potent... 

Since the blast door designs interfaces with the other structural components of a facility, it is wise to approach the preliminary design of the blast resistant door system early in the design stage of the project, As a minimum, door manufacturers will need the following information to furnish pricing and complete detail design of the doors ...
