Although the use of LVDTs boasts a high degree of accuracy, on the other hand it is limiting as it offers measurements between two points and it thus might be unable to capture localized deformations and strains over a bigger area of a structural specimen. In this aspect photogrammetry seems to offer certain advantages. Commercial solutions provide limited testing envelopes, while on the other hand, the wide range on new materials need more versatile techniques. Based on the need to develop an in-house photogrammetric toolbox to support several structural and material experiments in the department Advanced Pore Morphology (APM) aluminium foam specimens developed at Fraunhofer IFAM in Germany and cured at CUT, were tested under monotonic compressive load. Data acquisition, analysis and results, along with lessons learnt from the process are presented in this work.||Description:||ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume 3, 6 June 2016, Pages 35-41||URI:||https://ktisis.cut.ac.cy/handle/10488/14164||ISSN:||21949042||DOI:||10.5194/isprs-annals-III-5-35-2016||Type:||Conference Papers|
