MATDAT Project

MATDAT Project

Motivation

Proper selection of the material suitable for a specific application is one of the most important and complex issues that needs to be addressed ever earlier during product development. For modelling and simulation of the response of loaded structures and components, among other information, more or less intricate properties which describe material behaviour must be known. Except for the case of determining values of basic monotonic properties, experimental characterisation of material behaviour is complicated, expensive and, in the case of cyclic i.e. fatigue experiments, it can be long-lasting as well. If experimental testing of all candidate materials cannot be performed, which is usually the case, alternative solutions, such as literature research and estimation methods are often resorted to.

In light of this, it is suggested that the quality and accuracy of material selection can be improved by:

  • increasing availability, searchability and comparability of existing knowledge on materials,
  • developing better estimation methods and improving the accuracy and reliability of existing ones,
  • expanding the knowledge on proper application of estimation methods of material behaviour.

The Idea and Goals

The main idea behind MATDAT.com is at least partial fulfillment of above mentioned measures and making results of the project easily and widely available to the members of technical community (experts from the industry, engineers, designers, scientists, professors and students).

Our primary goals are:

development of a dedicated webpage featuring general information about the project,

an interactive, user-expandable knowledge base and material properties database containing published, design-oriented properties of design-relevant (at first) metallic materials,

a knowledge-based expert system for selection of a suitable estimation method and performing the estimation of advanced (cyclic, fatigue) material parameters from monotonic properties (such as the ultimate strength R m or Brinell hardness HB),

forming and supporting a user community willing to cooperate and share existing, published material data, either own, or available from existing literature sources.


Additional benefits (expected)

  • increased level of utilization of experimental equipment, as well as of experts’ work and knowledge,
  • easier and faster evaluation of more candidate materials during product development,
  • savings due to the avoidance of repeating experiments and tests already performed elsewhere with the same or similar materials,
  • increasing possibilities of verification of own experimental results,
  • facilitation of investigations and research requiring data on large number of materials,
  • dissemination of knowledge on advanced material models and an increase of their acceptance by practicing engineers and experts from the industry.

Lidija Runko Luttenberger, D. Sc.

Dear colleague,

Some twenty plus years ago I was writing my master’s thesis entitled “Contribution to practical determining of corrosion fatigue of steel with particular reference to offshore technology units”. My paper among other things contains fatigue and corrosion fatigue test results for microalloyed steel TStE355 FG36T. 
I would just like to reflect on how much effort and material resources I had to engage in order to provide  high-quality specimens appropriate for low-cycle fatigue tests and to obtain relevant results at the prestigious institute. I had to involve a number of people in two major Croatian shipyards for procuring, cutting and machining the specimens in the yards’ tools processing workshops and to do much travelling in order to attend the tests. On top of that, it was quite an undertaking to find the literature in the field at the time. I am not sure that much has changed since then so I welcome your initiative to institute a web page containing a collection of scientifically and professionally relevant test results regarding different materials. I am sure it will spare many the effort of undergoing the lengthy, demanding and expensive procedures of determining advanced characteristics of industrial materials.

Proficiency testing for aluminium alloy AlSi9Cu3

8. April 2014.
Talum Inštitut d.o.o., material research and environmental protection, invites laboratories to take part in proficiency testing for AlSi9Cu3 alloy (226a quality) by method of optical emission spectrometry in accordance with EN 14726, which will be carried out in May 2014. 

The material used is an AlSi9Cu3 alloy sample with the following composition: Si ? 9%; Fe ? 0,5%; Cu ? 2,5%; Mn ? 0,4%; Mg ? 0,3%; Cr ? 0,02%; Ni ? 0,01; Zn ? 0,1%; Ti ? 0,05%; Pb ? 0,01%; Ca < 0,01%; P < 0,01%; Sn < 0,01%; Sr < 0,01%; V < 0,01%
 
Participants will receive the samples by post in April 2014. Participation fee is 250 EUR and includes report, certificate of participation, sample and sample delivery. After you receive the report, you can use the sample as CRM. If you are interested in participation, please contact tatjana.vicko@talum.si

Deadline for application is 14.04.2014.
