1. A material in-situ test device under multi-load and multi-physical field coupled service conditions, in which a vertical asymmetric arrangement with three columns is adopted, comprising a support frame module, a shock isolation platform, a precise six-degree-of-freedom composite load applying module, a precise torsion module, a clamp and electrothermal coupling module, a digital speckle strain measurement and infrared thermal imaging module, an in-situ observation module, a precise indentation module and a circumferential positioning module,wherein the precise six-degree-of-freedom composite load applying module is connected to the support frame module by a stationary platform, and tension/compression and bending loads are applied on a test piece by means of the cooperation action of six electric cylinders,wherein the precise torsion module is provided on a movable platform of the precise six-degree-of-freedom composite load applying module,wherein the clamp and electrothermal coupling module is connected to the precise torsion module via a flange,wherein the digital speckle strain measurement and infrared thermal imaging module is provided on the shock isolation platform through an adjustable support base,wherein the in-situ observation module and the precise indentation module are provided on the circumferential positioning module to realize a rotatable in-situ observation on the test piece.
