Examination of analytical and finite element solutions regarding contact of a functionally graded layer
(Techno-Press, 2020)
In this study, the continuous and discontinuous contact problems of functionally graded (FG) layer resting on a rigid foundation were considered. the top of the FG layer was loaded by a distributed load. It was assumed ...
Reply to the discussion by Granier of Vincent et al., (2018) (Marine and Petroleum Geology, 91, 639-657)
(Elsevier Sci Ltd, 2020)
Granier (2019) questioned the identification of a number of foraminifer species within the study of Vincent et al. (2018). We dispute his findings and provide supporting evidence for our original identifications. Our ...
