Introduction As one of the rheological properties[1], rock creep is an important mechanical characteristic of rock-like materials especially for the deep mine rocks under long-term static-load, whose strengths tend to decrease gradually and the rocks show obvious creep characteristics.
As MTS rock mechanical test system was used in this study, the loading in the experiment is dynamic stability with high electricity consumption, loading time cannot be very long and obvious creep will take place for coal of soft materials in short time, therefore, every stress level was loaded for two hours in this experiment.

The material used in this study is a stainless thin plate with 1mm height.
In real time welding, the CCD camera will capture more noise including arc light, material reflection, which will bring more difficulty in image processing, if the working height of the CCD camera is oversized.

They are relatively low cost materials offering possibility of biodegradation.
Bio-based materials derived from natural oils, such as castor, palm, canola and soybean oils in the form of natural polyols were used as raw materials in the preparation of bio-based elastomeric polyurethanes (PU) [1].
The properties of PUs were governed by the nature of raw materials—polyol and isocyanate.
