National Physical Lab opts for a full measure of Ansys FE software
IDAC UK, a leading design software consultancy, today announced that the UK's National Physical Laboratory has purchased ANSYS Multiphysics design optimization software to support its classical and advanced modeling needs in the development of engineering materials and nanotechnology As the UK's national standards laboratory, the National Physical Laboratory (NPL) underpins the national measurement system, ensuring consistency and traceability of measurements throughout the UK

The NPL provides an integrated approach to materials problem solving based on its broad metrology experience of test method development, mechanical testing, materials data, software modeling, lifetime prediction, standards and knowledge transfer activities.
According to Dr David A.
Mendels of the NPL's Materials Modeling and Nanotechnology group (Materials Centre), modeling and testing is particularly challenging in this arena, where the relevant scale is close to or smaller than the limit of continuum mechanics.

Says Dr Mendels, "The development of new materials structures/devices in the Nanotechnology area inevitably involves the design of a wide range of nanoscale artifacts involving materials where multiple interfaces exist, e.g super-lattices, Nanocomposites, bio-materials and semi-conductors.
Such designs require an understanding of the behavior of materials at the nanoscale, and the development of the measurement methods needed to determine model input parameters, i.e the properties of materials at the nano/sub-micron length scale.
One of the objectives of our group is to develop methods where classical design based on continuum mechanics break down, as the presence of interfaces between different phases have a significant effect on properties and behaviour." "In our analysis of dynamic and static mechanical models of non linear phenomena, ANSYS will be mainly used for solving for large deformations and strains for a range of experimental geometries, in order to design novel test methods.
Modeling allows us to design right at the first time, and to check that the test is adequate for the measurement of a particular parameter.
In this sense, the use of parametric tools is valuable, as it permits to maximize the signal/noise ratio of the material's response." He adds, "We will also be analyzing models of piezoelectric materials and systems, including sub-modelling of circuits.
We are more interested by piezo-composites and thin films nowadays, as well as the indentation response of these systems.
NPL is developing novel measurement devices and is using FE to optimise and gain better understanding of the coupling between mechanical and electronic response of the materials.
We will also be examining classical fluid flow problems involving the design of flow cells for biological applications, using FLOTRAN." IDAC UK provides Finite Element Analysis and Computer Aided Engineering Consulting, and is a leading provider of ANSYS and DesignSpace software.
ANSYS Multiphysics offers a common platform for fast, efficient and cost-effective product development, from design concept to final-stage testing and performance validation.
