| Abstract Scope |
Nanomechanical tests have become impactful nuclear materials methods. When done correctly, they offer information on the mechanisms of material deformation and failure. However, numerous trials and errors go in to determining the correct size, shape, and test parameters to generate effective data. This talk will highlight the lessons learned in a series of small-scale mechanical tests, from ion irradiated micropillar compression to size-dependent cantilever fracture to specimen shaping effects. It demonstrates the importance of correlating plastic zones and irradiation damage in compression, considering the specimen dimensions for appropriate tests, and issues around repeatability of nanoscale experimentation. Through a decade of insights from learning from failures, this talk will present recipes for success, or well, avoiding similar pitfalls.
