Elastica®

Elastica makes the complicated theory of contact mechanics available in a user friendly and very fast form (no Finite Element Method):

The main applications of Elastica are:

• Investigation of elastic stresses, strains and deformations in coated surfaces during mechanical load and impact (normal and lateral).
• Investigation of the load carrying capacity of surfaces.
• Optimization of coatings for mechanical protection and support of the coating design.
• Analysis of indentation, scratch and wear tests and support for the design of such experiments.

The advantages of Elastica compared with Finite Element or Boundary Element calculations are:

• The calculation is about 1000 times faster due to the use of complete analytical solutions. This enables a real multi−parameter search and optimization.
• Sharp stress peaks and the position and dimension of the contact area are well resolved.
• Up to three layers on a substrate with thicknesses between some nanometer and several meters can be considered without redesign of the contact geometry.
• Calculations of non−rotational symmetric contact problems, caused by tangential forces in one direction, can be done with the same calculation speed.

Main assumptions of the model:

• Ideally flat surface and interfaces
• Homogeneous and isotropic materials
• Ideal adhesion of the coatings

In many cases deviations from these assumptions are not that restrictive as first suspected. Despite all idealizations the model delivers in most cases feasible results. If you are not sure whether you can examine your contact problem with Elastica, please contact us.

IndentAnalyser®

IndentAnalyser is the only instrument independent software for the analysis of depth sensing indentation measurements (IIT) with Nanoindenters as well as Macroindenters with a multitude of functions. This includes for example:

• Simultaneous reading, presentation and analysis of up to several hundred indentation measurements.
• Analysis of indentation modulus, indentation hardness, Martens hardness, equivalent Vickers hardness, indentation creep, energies according to DIN EN ISO 14577 and more than 60 additional parameters.
• Zero point correction automatic or manual.
• Thermal drift correction automatic or manual.
• Radial displacement correction and variable epsilon factor.
• Averaging of measurements with equal load and equal sequence, even for different number of data points.
• Clearly arranged presentation of results with statistics in a table, a graph or as report
• Export of data in different image formats, as text, in EXCEL, XML or HTML format
• Determination and correction of instrument stiffness or compliance
• Determination and application of indenter area function or radius function (for spherical tips) with maximum two reference materials.
• Analysis or purely elastic measurements with spherical tips and complete elimination of the substrate influence for the calculation of the Young’s modulus. T herefore this module can be applied to measurements of ultra−thin and hard coatings of only 20nm or less.
• Analysis of creep behavior and calculation of creep rate
• Modeling of force−displacement curves (loading and unloading) after specification of force, indentation hardness and modulus, also under consideration of the real area function.
• Analysis of dynamic measurements with continuous or quasi−continuous stiffness measurements (CSM) (only UNAT, ZHN, Nanoindenter XP und G200)
• Analysis of lateral force−displacement measurements (only UNAT and ZHN) for example in scratch or wear tests.
• Materials database with parameters like E−modulus, Poisson’s ratio, density, yield strength, thermal expansion and other for about 630 materials.

To analyze the data it is necessary for most of the instruments to convert them in text format. This can be done with the export function of the original software. This is done through the respective export routines. The user manual gives some hints.

The software is applicable to data from the following commercial instruments

ASMEC UNAT (no text format necessary)
CSM / Anton Paar NHT/UNHT
Elionix ENT−1100
Helmut Fischer Fischerscope (all instruments, DOS or Windows data format)
Hysitron, all instruments
Keysight/Agilent Nanoindenter XP/G200
Micro Materials Nanotest
Shimadzu DUH−202
Shimadzu DUH−W201
UMIS−2000 (DOS and Windows data format, no text format necessary)
Zwick ZHN (no text format necessary)
Zwick ZHU

Further data from different non−commercial research instruments can be read.
