Abstract:
1. A device for force measurement in dynamic tensile experiments on material samples, comprising a force measuring cell, in which at least one force measuring sensor is integrated and which is executed one piece with a first connecting structure, with the material sample being connectable in a firm, detachable manner via said first connecting structure with said force measuring cell, which is provided with a second connecting structure, which is disposed opposite said first connecting structure and via which said force measuring cell is attachable to a fixed back-rests, wherein at least two force measuring sensors are disposed on said force measuring cell spaced from said first connecting structure in such a manner that the distance between said at least two force measuring sensors and said first connecting structure, and between said at least two force measuring sensors and the tensile sample, is smaller than the distance between said at least two force measuring sensors and said second connecting structure, said force measuring cell is provided with a housing or with two pressure plates, which has, respectively have, a thinner wall thickness in the region of said force measuring sensors than in the other housing region or other regions of said pressure plates, and said force measuring cell has more a stable type of construction regarding elastic deformability in the region of said second connecting structure than in the region of said first connecting structure and said at least two force measuring sensors.
