Sure, Frantisek - we are developing micro/nano stress measurement approaches for _all_ kinds of materials (metals, composites, carbon fibres, coatings, mineralised biological tissues, bulk metallic glasses etc.) using the micro-ring-core method in the Oxford MBLEM lab (www.korsunsky.org)
This is done as part of iSTRESS consortium funded by EU.

I have some research paper do simulation in residual stresses specifically for wood polymer composite. However, for experimental in measuring residual stresses i recommend use hole drill mehod. Please visit this website (www.sintechnology.com).
