Regarding this, buckling deformation which is caused by thermal stress is one of the undesired mechanical properties which must be alleviated. As buckling deformation is more observable in hard to process materials, silver is selected to be studied theoretically and experimentally for this paper. Different scanning strategies are utilized and a Finite Element Method (FEM) is applied to calculate the temperature gradient in order to determine its effect on the buckling deformation of the objects from experiments.}, language = {en} } @inproceedings{GabrielliMathiesGrossmannetal.2015, author = {Gabrielli, Roland Antonius and Mathies, Johannes and Großmann, Agnes and Herdrich, Georg and Fasoulas, Stefanos and Middendorf, Peter and Fateri, Miranda and Gebhardt, Andreas}, title = {Space Propulsion Considerations for a Lunar Take Off Industry Based on Regolith}, series = {International Symposium on Space Technology and Science (ISTS).
