Apparatus to test the mechanical characteristics of a test object presses a spike into the surface, with monitors to register the path movement and the environment at the contact point

摘要

#CMT# #/CMT# The apparatus to test the mechanical properties of a test object (26) presses a spike (16) into its surface (32). A path movement monitor (28,29) registers the pressing path length. A further interferometer (30,31) registers the dent in the object in the environment at the contact point between the spike and the object. The action is observed by a microscope. #CMT#USE : #/CMT# The apparatus tests the mechanical characteristics of a test object. #CMT#ADVANTAGE : #/CMT# An object of a material which is not homogenous can be tested. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side view of the test apparatus. 8 : solder inclusion 15 : spike mounting arm 16 : spike 18 : measurement arm 26 : test object 27 : press direction 28,29 : path movement monitor 30,31 : interferometer 32 : object surface.
