A tensile testing apparatus is provided, and generally includes an X-Y automated stage, and a first specimen holder for holding and transferring force to a specimen to a first portion of a specimen. The first specimen holder is operatively supported by the X-Y automated stage. A Z-automated stage, a multi-function nanotensile transducer head assembly, and a second specimen holder for holding and transferring force to a second portion of the specimen is further provided. The second specimen holder is operatively linked to the Z-automated stage via the nanotensile transducer head assembly. Variable displacement modalities, and non-Z alignment assessment and adjustment are enabled by the multi-function nanotensile transducer head assembly, as well as the X, Y, and Z automated stages.
A tensile testing instrument comprising:
A tensile testing instrument comprising:
A multi-function test assembly for operative engagement with a specimen holder of a tensile testing apparatus, said multi-function test assembly comprising a piezo-actuator, force sensing means, and displacement sensing means, said force sensing means operatively linked to said piezo-actuator so as to delimit a load cell subassembly, said displacement sensing means being operatively coupled to said load cell subassembly by a shaft and disengageable therefrom, said shaft adapted so as to disengage said displacement sensing means from said load cell subassembly.
A multi-function test assembly for operative engagement with a specimen holder of a tensile testing apparatus, said multi-function test assembly comprising a piezo-actuator, force sensing means, and displacement sensing means, said force sensing means operatively linked to said piezo-actuator so as to delimit a load cell subassembly, said displacement sensing means being operatively coupled to said load cell subassembly by a shaft and disengageable therefrom, said load cell subassembly having a first operative status delimited by displacement of said load cell subassembly by said displacement means.
