Dynamic Triaxial Tests of High‐Strength Concrete
Journal of Engineering Mechanics, 1989Dynamic triaxial compression experiments were performed on a limestone-aggregate concrete whose unconfined static compressive strength is about 100 MPa. The axial strain rates ranged from 0.5/s to 10/s, the confinement levels ranged from zero to 124 MPa, and the peak axial loads ranged from 103 MPa to 393 MPa.

Soil Dynamics and Earthquake Engineering, 2020
Abstract A series of dynamic direct shear tests and triaxial tests were conducted to investigate the dynamic properties of the warm frozen soil along the Qinghai-Tibet railway. The relationship between dynamic shear stress and dynamic shear strain of frozen soil under relatively high negative temperature is given according to the test results.

Identifying fatigue damage of mudded intercalations based on dynamic triaxial test
Engineering Geology, 2021Abstract Fatigue damage caused by cyclic dynamic loading may deteriorate strength parameters of mudded intercalations. This research work aimed at defining a new fatigue damage variable expression and revealing the fatigue damage evolution laws of mudded intercalations by conducting dynamic triaxial tests.

Servo-controlled equipment for dynamic triaxial testing of soils
Géotechnique, 1972THIS NOTE OUTLINES THE DETAILS OF THE LATEST SERVOCONTROLLED HYDRAULIC TYPE OF MACHINE FOR SOIL TESTING. TWO IMPORTANT FEATURES OF THIS TYPE OF APPARATUS ARE THAT PROGRAMMED STRESS CHANGES WITH TIME CAN BE APPLIED WITHOUT BEING AFFECTED BY CHANGES IN SAMPLE BEHAVIOR DURING THE TEST, AND THAT ANY TYPE OF COMPLEX WAVEFORM OF LOADING CAN BE READILY ...

Large triaxial test study on dynamic characteristics of round gravel
Arabian Journal of Geosciences, 2020A series of large-scale drained dynamic triaxial tests were conducted on Nanning saturated gravel soil to investigate dynamic characteristics. The effects of relative density, dynamic stress amplitude, and the number of load cycles on the pore pressure, accumulation strain, and stress–strain hysteresis loops of saturated round gravel soil were analyzed.

Dynamic soil property measurements during triaxial testing
Géotechnique, 1989Offshore site investigations are discussed, and a description is given of a method of measuring the compression wave velocity, the shear wave velocity, and hence G sub max (initial tangential shear modulus of a soil), simultaneously with the routine investigation of soil properties using the triaxial cell.
