A cement-based stabilizer is effective in stabilizing the peat soft ground with extremely high compressibility and low shear strength for road construction. Moreover, stabilized soil occasionally fractured reused embankments, depending on construction site conditions. In such circumstances, subjected to stress history owing stabilization, crushing, reconstitution. this study, evaluate implicati...

Articular cartilage exhibits anisotropic mechanical properties when subjected to tension. However, mechanical anisotropy of mature cartilage in compression is poorly known. In this study, both confined and unconfined compression tests of cylindrical cartilage discs, taken from the adult human patello-femoral groove and cut either perpendicular (normal disc) or parallel (tangential disc) to the ...

For prevention of soil compaction, knowledge of allowable compression stress limit (compaction strength) in soil is important. Pre-compaction stress ( σpc) was introduced as soil compaction strength and often used as a criterion for evaluation of soil susceptibility to compaction. In this research, pre-compaction stress was measured for a sandy loam soil with plate sinkage (PST) and confined co...

Abstract The flat joint contact model (FJM) provides significant improvements over its predecessors, the parallel bond and models, for bonded particle modelling of rocks due to unique microstructure that allows reproduction macroscopic compressive–tensile strength ratio, σ c /|σ t | ; internal friction angle, ϕ Hoek–Brown constant, m i . However, microproperty calibration process is tedious tim...

The focus of this paper was directed towards investigating the influence multiple freeze–thaw (FT) cycles on mechanical behaviors an expansive soil under a wide range confining stresses (σc) from 0 to 300 kPa. Consolidated undrained (CU) shear tests with pore pressure measurement (σc = 10–300 kPa) and unconfined compression (UC) were conducted FT impact specimens derive shearing stress–strain r...
