A simplified five-point inverse analysis method to determine the tensile properties of UHPFRC from unnotched four-point bending tests

The analytical basis on which the method is based, justification of key point selection, and the process followed to achieve the simplified formulation, which allows dispensing with the use of a computer, are presented. An application example on a UHPFRC unnotched four-point bending test specimen, and its comparison with a point-by-point inverse analysis, are included.
