The effect of experimental and microstructural parameters

Triaxial compression tests were conducted on cold-pressed calcite, aragonite and limestone aggregates and on Solnhofen limestone specimens to study the effect of experimental and microstructural parameters on the transition from brittle failure to cataclastic flow. The tests were performed at confining pressures up to 195 MPa and at strain rates between 5 10 SUP -4 /SUP …

Multiscale deformation processes during cold sintering of

May 01, 2020 Pressure solution creep is a cold sintering process that enables the transport of atoms from inter-particle contacts to pore walls in a similar fashion to the conventional densification and sintering of ceramics at high temperatures. This mechanism is expected to dominate the creep deformation of geological calcite for pressures up to 500 MPa .
