iWeld featured at the annual ASNT Research Symposium in Pittsburgh, PA, USA, between the 24th and 28th of June 2024. Lucas Queiroz Machado from the University of Southampton presented a paper on the framework for determining complex elastic tensor for heterogeneous materials with elongated grains. This is a homogenisation procedure that captures the attenuation of ultrasound propagating across columnar grains. The resulting homogenised complex tensor can be used in fast ray-based simulation to establish measured signal loss in a weld. These results were developed as a part of Work Package 2 of the iWeld project.
