|発明の名称||MULTIAXIAL LOAD TESTING DEVICE AND METHOD|
PROBLEM TO BE SOLVED: To provide a multiaxial load testing device and method capable of carrying out an accurate load test in a multiaxial state.
SOLUTION: A multiaxial load testing device includes a pressure container portion 5 formed with a storage hole 50 for storing a specimen 100, and collecting hydraulic oil around the specimen 100 stored in the storage hole 50; an axial pressure applying portion 6 for applying a load to the specimen 100 in an axial direction; an inner pressure applying portion 7 attached to the axial pressure applying portion 6, and applying inner pressure to the specimen 100 by the hydraulic oil collected in the inside space of the specimen 100; an outer pressure applying portion 8 for moving the specimen 100 in the axial direction and applying outer pressure to an outer periphery of the specimen 100 by the hydraulic oil; and a twist applying portion 9 attached to the outer pressure applying portion 8, and rotating an operation body 82 of the outer pressure applying portion 8 to apply a twist load to the specimen 100 connected and fixed to the operation body 82.
