changes, can be derived from the magnetic hysteresis loop[10-13]. Q235 steel of wide availability has been finding greater application in varieties of fields of national economic construction, so... tests were performed on Q235 steel tubular model specimens in NIM-2000HF magnetomechanical coupling equipment. The hysteresis loops were obtained in different magnetic fields and stresses......
on the Voronoi joint network can simulate the loading and unloading mechanic characteristics of irregular columnar jointed rock. It can explain the significant compaction and hysteresis loop effect in the rigid bearing plate test of columnar jointed rock mass. 3) Restricted by the two-dimensional model, the hysteresis loop effect is only analyzed in the vertical load direction. Study of next step......
ratio. The existence of "training" and "memory" effects in red sandstone under cyclic point loading was proved. Key words: red sandstone; cyclic point loading; fatigue life; hysteresis loop... formed a hysteresis loop in each load cycle. The loops changed their slopes and density gradually with increasing the cycle number, and were affected by the lower limit load and frequency. Here......
