Ces Cambridge Engineering Selector Software Developer

CES Selector. A unique PC-based software product supporting systematic selection of materials for engineering applications. (NASDAQ: ANSS), the global leader and innovator of engineering simulation software, announced that it has entered into a definitive agreement to acquire Cambridge-based Granta Design, the premier provider of materials. Cambridge Engineering Selector ME 471 PROJECT – Spring Semester 2005. SOFTWARE SUMMARY. The Cambridge Engineering Selector (CES) is a powerful tool for the evaluation and selection of materials for engineering design. It has two main components: Selector and Constructor.

SOFTWARE SUMMARY

The Cambridge Engineering Selector (CES) is a powerful tool for the evaluation and selection of materials for engineering design. It has two main components: Selector and Constructor. Selector incorporates a set of seven data tables (materials, manufacturing processes, structural sections, suppliers, references, uses and industrial sectors). Constructor is a tool for making and editing selection databases for use in Selector.

Most providers support kill switches in Windows these days, but not necessarily in macOS, and even less so in mobile apps.Android v7+ users are in luck, however, as the OS now includes a VPN kill switch which works with any installed VPN app. Why do I need one?A “kill switch” prevents internet connections when the VPN is not running, thus ensuring against accidental exposure of your IP when torrenting in the event of a VPN drop-out, software crash, when switching between networks. It is, therefore, a vital tool for torrent users.Do make sure that your chosen VPN service offers a kill switch for the platforms you torrent on. Rarbg.

The databases used in CES contain the mechanical, thermal, and electrical properties of a wide range of materials including ceramics, metals, polymers, elastomers and composites. Property data is presented is a graphical format to provide a series of “material selection charts”, which, when combined with the use of performance indexes, enable the rapid identification of the optimum materials for a specific design.

SOFTWARE AVAILABILITY

CES is only available in the machines at IPL. The online help provided along with software is quite explanatory and can be explored for guidance.

PROJECT GUIDELINES

Listed below are three components for which you must use CES to select a suitable material based on the given requirements.

1. IC Engine Piston

Select a material for piston with the following properties:

Ø Density < 6 Mg/m3

ØTensile Strength > 40 MPa

Ø Price < 15 GBP/kg (1 GBP = $1.50)

ØMax Service Temperature > 350 K

ØFracture Toughness > 20 MPa.m1/2

Ø Forming must be Hot Closed Die Forging

2. Ball bearings

Select a material for bearings with the following properties:

ØEndurance Limit > 425 MPa

Ø Hardness > 1500 MPa

ØModulus of Rupture > 400 MPa

ØTensile Strength > 1000 MPa

ØMaximum Price < 0.5 GBP/kg

Ø Wear Very Good

3. Fireplace Walls

Select a material for fireplace walls with the following properties:

ØThermal Conductivity < 45 W/m.K

ØThermal Expansion Coefficient < 8E10-6 /K

ØMelting Point > 1000 K

Ø Price < 1.5 GBP/kg

ØMax Service Temperature > 400 K

Ø Flammability Very Good

Sample Problem: (explained during Demo)

Fastener for Aircraft Applications:

Select a material for a fastener walls with the following properties

Ø Density < 2.2 Mg/m³

ØElastic Limit > 65 MPa

^ØFracture Toughness > 12 MPa.m^1/2

ØHardness > 250 MPa

Ø Forming must be Shell Casting

Forming must be Standard Machining - Automated

Once a comprehensive materials list has been compiled for each of the scenarios, a brief report should be created outlining the findings. This report should include a complete list of potential materials for each scenario (no single list will exceed 20), an explanation of which material your group thinks is best suited for the given application, and an explanation of why each of the other materials is insufficient. Also upload your saved CES file to sambadfscoursesgroupme471 groupno.

This is a MANDATORY group project (work together with your design group). You should turn in the report on or before March 04(please hand it to TA or put it in Bhushan Ekbote’s mail box at EB2518). If you have any questions pertaining to this project or the report, please contact design TA.
