The ASA (now ANSI) performance code for Safety Glazing Materials was revised in 1966 to incorporate these improvements in windshield constmction. The addition of test no. 26 requiring support of a 2.3-kg ball dropped from 3.7 m defined this level of improvement. It was based on a correlation estabUshed between 10-kg, instmmented, head-form impacts on windshields, on 0.6 x 0.9-m flat laminates, and the standard 0.3 x 0.3-m laminate with the 2.3-kg ball (28). Crash cases involving the two windshield interlayer types were matched for car impact speeds and were compared (29). The improved design produced fewer, less extensive, and less severe facial lacerations than those produced in the pre-1966 models. 

We previously encountered failure modes and effects (FMEA) and failure modes effects and criticality analysis (FMECA) as qualitative methods for accident analysis. These tabular methods for reliability analysis may be made quantitative by associating failure rates with the parts in a systems model to estimate the system reliability. FMEA/FMECA may be applied in design or operational phases (ANSI/IEEE Std 352-1975, MIL-STD-1543 and MIL-STD-1629A). Typical headings in the F.Mld. A identify the system and component under analysis, failure modes, the ef fect i>f failure, an estimale of how critical apart is, the estimated probability of the failure, mitigaturs and IHissihiy die support systems. The style and contents of a FMEA are flexible and depend upon the. ilitcLiives of the analyst. 

Just another approach is to calculate e.g. the temperature distribution within a separate program like ANSYS, figure 14, and to transfer the temperature induced index change to the 10 design. If the refractive index change due to the heater can be represented in a parametric model of a... 

Quality Systems — Model for Quality Assurance in Design, Development, Production, Installation, and Servicing, ANSI/ ASQC Q9001-9004, American Society for Quality Control, Milwaukee, WI, 1994. 

In this chapter we will summarize the needed facilities for the physical modelling of the material and the flow conditions, which the chosen CFD-code must provide. We focus on the design of the models in ANSYS/ FLOTRAN and ANSYS/CFX, but the specifications will be kept generally applicable to other commercial codes. 

IEC 61165 and ISA TR 84.00.02-4 illustrate the Markov modelling technique for calculating the probabilities of failures for safety instrumented functions designed in accordance with lEG 64511-1 ANSI/ISA-84.00.01-2004 Part 1 (IEC 61511-1 Modi and this standard. 

Computational fluid dynamics (CFD) based on the continuum Navier-Stokes equations Eq. 2 has long been successfully used in fundamental research and engineering design in different fluid related areas. Namrally, it becomes the first choice for the simulation of microfluidic phenomena in Lab-on-a-Chip devices and is still the most popular simulation model to date. Due to the nonlinearity arising from the convention term, Eq. 2 must be solved numerically by different discretization schemes, such as finite element method, finite difference method, finite volume method, or boundary element method. Besides, there are a variety of commercially available CFD packages that can be less or more adapted to model microfluidic processes (e.g., COMSOL (http //www.femlab.com), CFD-ACE+ (http // www.cfdrc.com), Coventor (http //www. coventor.com), Fluent (http //www.fluent.com), and Ansys CFX (http //www.ansys.com). For majority of the microfluidic flows, Re number is... 

Software suite is a modem ANSYS-14/CFX-modeling tool, based on the numerical solution of the equations of hydrodynamics [1, 2], Hydro-dynamic calculation makes it possible to determine the flow resistanee of the device and to predict the eflfieiency of the separation proeess in the design stage. 

The program ANSYS-14/CFX mathematical model of motion of polydispersed gas system. The character of the movement of dust particles under the influence of centrifugal force. This allowed choosing the desired hydrodynamic conditions and taking into account of the design under various conditions of scrubber. Experimental study of the hydrodynamic characteristics of the device to determine the empirical constants and test the adequacy of the hydrodynamic model. 

The mathematical model of the mechanical actuator system can be developed directly from the CAD design drawing by means of commercial FEM software tools, e.g. ANSYS [3]. This model is fundamental for the calcula-tional modal analysis which serves to find out the systems natural frequencies. Figure 6.10 shows the FEM model of the active piezo absorber and gives an impression of the third vibration mode of the structure which is used in this example for the vibration absorption. 

ANSYS Inc designs and licenses simulation software, widely used by engineers and designers in several areas. Modelling. 

Voltage drop in an odd-shaped geometry can be calculated accurately only with numerical techniques. The easiest way is to use software tools (such as ANSYS Thermal Analysis System (TAS) Thermal Modeling Software) that are designed for this type of problem.
