In-situ mechanical loading testing is a division of field testing where the sample is tested in place without changing the environment. It is able to give information on the structural evolution of material in microscopic level. This has been widely used to study the tensile or compressive behavior of materials. Design of in-situ testing device has been developed in various fields for practical reasons. This project is an industrial collaboration between Nanyang Technological University and Singapore Institute of Manufacturing Technology (SIMTech). To implement the combination of in-situ mechanical loading and micro-Computed Tomography, the design and assembly of a mechanical loading stage is investigated. The design and fabrication of a load cell was done and assemble on the inspection system in SIMTech for the purpose of applying compressive load to the sample and obtaining the resulted scanning images of internal structure simultaneously. Ex-situ compression test on syntactic foams was performed to give the data needed for performing in-situ compression test on the same material. Some recommendations for the load cell are presented to optimize the load cell.
