triaxial loading and unloading
(OP)
using a triaxial cell, can a shear stress be "applied" by holding the confining stress constant and reducing the verticle stress? if so, how does this show up on a plot of the stress history on a p-q plot?

we have 2 different kind of triaxial testing:
1- Compactional Testing(C.T)
2- Extentional Testing(E.T)
in this case that u mentioned,it is extentional testing
and this kind of testing shows extentinal behaviour of soil
(tentional behaviour);
but Compactional method(that is custom)shows compactional
behaviour of soil.
the shear strength of soil is much lower in E.T method because
as u know soil is weak in tention.
BUT:loading an unloading and reloading is somthing else.it is
usually used in C.T method.
OFCOURSE we have other methods exept C.T &E.T method to see other
parameters like G(shear modulus).

C.T method =Compressional Test not compactional...
so we have compressional and extentional test.
