Key to Metals, now rebranded to Total Materia, is a vast database which contains the properties of metallic and non-metallic materials, providing a turn-key solution for the global engineering community. Designed to help a broad range of engineering professionals, Key to Metals is specialized in helping to find and source similar and equivalent materials worldwide, getting easy-to-use and accurate material properties, and navigating through international standards. Besides the “standard” dataset which includes mechanical and physical properties at various temperatures, chemical compositions, international cross-reference tables and more, Total Materia also presents a unique collection of advanced properties, such as stress-strain curves, cyclic properties, fracture mechanics, and creep, specifically developed to serve the engineering community with mechanical and physical properties essential for accurate advanced CAE (Computer Aided Engineering) calculations and simulations. The Total Materia database with advanced CAE properties included has been available to Altair users to through the HyperWorks Partner Alliance (HWPA) program from the beginning of 2012 and has enjoyed broad popularity among the Partner Alliance user base, with more than 500 users and the number growing every week. The fact that this is the first Web application within the APA provides an interesting opportunity to analyse CAE users’ behaviour and patterns in using a material properties database, showing that users have interest in both conventional material properties, material comparison and cross-referencing, as well as in advanced properties, thus providing additional benefits to Altair customers beyond pure CAE usage. High exposure and positive feedback received in the first year of service prompted the development and launch of the Total Materia Premium Edition, an Altair-exclusive Web application that combines the previous functionality with a unique possibility to seamlessly export data to HyperWorks software and includes the properties of polymers, ceramics and composites. As a result of the additional new functionalities, more than 70% of Altair users utilized Premium Edition instead of the Standard. New developments in 2014 include a completely new software edition that is to be launched with HyperWorks 13.0 and, as an alternative to the existing independent Web interface, and provides the complete functionality of Total Materia Premium Edition in a tight integration with HyperWorks software. Through a specially developed Web Service API to Altair software, HyperWorks users get an opportunity to seamlessly query the Key to Metals database and utilize any of its 6 million material property records without leaving the HyperWorks environment and their simulation task.

DEVELOPMENT OF A NEW ALTAIR-CUSTOMIZED DATABASE OF ADVANCED MATERIAL PROPERTIES

  1. 1. www.keytometals.com ATC Europe Munich, June 2014 Prof. Dr Viktor Pocajt, Daan Bosman New Developments on Altair-Customized Database of Advanced Material Properties 1Key to Metals - The World’s Most Comprehensive MATERIALS Properties Database
  2. 2. www.key-to-metals.com
  3. 3. www.key-to-metals.com Engineering Metals Properties Requirements • Challenge - Engineers need precise material properties information • Today - Most of CAE packages have some material libraries, but they are either empty or populated with only a handful of most common materials • Engineers need to search and occasionally find some data in scattered sources such as standards, books, articles and the Internet, some of them being even free • Results in… 3Key to Metals - The World’s Most Comprehensive METALS Properties Databases
  4. 4. www.key-to-metals.com 4Key to Metals - The World’s Most Comprehensive METALS Properties Databases 5) Time wasted on searching for properties instead of engineering 4) Lost opportunities to optimize design 3) Difficulties in communication with purchasing and manufacturing, especially internationally 2) Creating islands of information within the organization 1) 29.3% of all failures are caused by poor design or lack of knowledge about material properties and standard specifications!
  5. 5. www.keytometals.com Example 5Key to Metals - The World’s Most Comprehensive METALS Properties Databases Yield stress Aluminum: 240-310 MPa Stainless steel: 275-350 MPa Carbon steel: 205-275 MPa www.engineersedge.com
  6. 6. www.key-to-metals.com Is it? • Aluminum (240-310 MPa ???) • Grade 1060, ASTM B 736, Plates, sheets; Annealed (O); 1,295 - 76,2 mm; YS = 17 MPa • AA 2014, Plates; Solution heat treated and artificially aged (T62); 12,7-25,4 mm; YS = 407 MPa • Stainless steel (275-350 Mpa ???) • S30403, ASTM A 814; Pipes; Heat treated; YS = 170 MPa • Type 630, ASTM A 693, Plates, sheets, strips; Precipitation hardened (PH496); YS = 1070 MPa • Carbon steel (205-275 MPa ???) • A 1008 EDDS, ASTM A 1008; Sheets; Cold rolled; YS = 105 MPa • 42 NCD 16-M , AFNOR NF A 32-058, Castings; Quenched and tempered (Class 1); YS = 1500 MPa • Dependency on the heat treatment • S21400, ASTM A 580; Wires; Annealed; YS = 345 • S21400, ASTM A 580; Wires; Cold drawn; YS = 1310 • The ratio is ~3,8:1 ! 6Key to Metals - The World’s Most Comprehensive METALS Properties Databases
