PROGRAMMED SIMPLE SHEAR TESTING OF SOILS

DEVELOPMENT OF THE PROGRAMMED SIMPLE SHEAR TEST REPORTED HERE IS BASED ON THREE CONSIDERATIONS: (1) FOR A BASIC UNDERSTANDING OF THE CONSTITUTIVE RELATIONS OF SOILS, SHEAR AND VOLUMETRIC STRESS SHOULD BE CONSIDERED SEPARATELY; (2) ANALYSIS OF EARTHQUAKE EFFECTS PLACES A HEAVY DEMAND ON STRESS--STRAIN RELATIONS FOR SOILS; AND (3) AVAILABLE SIMPLE SHEAR TESTS ARE DEFICIENT IN PRODUCING BOUNDARY CONDITIONS NECESSARY FOR A UNIFORM STATE OF SIMPLE SHEAR IN THE TEST SPECIMEN, AND ALSO LACK THE SENSITIVITY REQUIRED FOR ACCURATE DEFINITION OF THE STRESS--STRAIN RELATION FOR STRAINS LESS THAN ABOUT 0.1%; AND (4) PROGRAMMABLE LOADING IS NEEDED TO STUDY THE SHEAR BEHAVIOR OF SOILS UNDER GENERAL LOADING PATHS THAT DO NOT SIMPLY INVOLVE STRESSES OR STRAINS WITH CONSTANT AMPLITUDE AND FREQUENCY. THE TESTING DEVICE APPLIES LOADS ELECTRO- MAGNETICALLY AND UTILIZES A HOLLOW CYLINDER SPECIMEN. THE DEVICE, TEST PROCEDURES, AND SAMPLE RESULTS ARE DISCUSSED AND EXPLAINED.
