    Coefficient of friction of elastomer on steel

    1. yes, water will be used to test the weld. No. 2. yes 3. Actually, I want to measure both static and kinetic friction. 4. I am using only cylindrical . 5. only one seal 6. I can't use back up ring or anti extrusion device because of complexity.

    Coefficient of friction of elastomer on steel

    You are right. I want to perform it with different confining pressures with different lubricants. The application of the product is in pipeline welding test. The size of the product is 4inch diameter with 31mm thickness. I do not have two axis universal testing machine.

    Coefficient of friction of elastomer on steel

    In my project in real world, the elastomer seal will take much higher load even 1000 bar. Now I want to test the friction according to pressure. I will control the vertical load before extrusion of elastomer and in this case, how I will give the horizontal load on the steel. It will be helpful...

    Coefficient of friction of elastomer on steel

    I want to develop a set up for the measurement of co-efficient of friction of elastomer rubber in contact with steel. I have attached a drawing for information. Here, I will apply vertical load through universal testing machine and then I want to apply another tensile load horizontally. But I...

    Coefficient of friction of elastomer on steel

    Thanks . Actually, I have machined the pipe wall thickness and made a gap 3mm in between the elastomer seal and pipe wall. Then I have added compression load to 30 KN and then the seal deformed and contacted the pipe wall. I measure the contact pressure by some pressure strip but I got some...

    Coefficient of friction of elastomer on steel

    I have to apply 30 KN force on the elastomer and then it will deformed. When the elastomer seal contact width the pipe wall then I need to measure the contact pressure and friction co-efficient of elastomer steel pipe seal.

    Coefficient of friction of elastomer on steel

    Thank you for your reply. My situation is different. I have to measure friction co-efficient of elastomer rubber and steel contact. This rubber is used in the pipe for sealing purpose. Rubber dimensions are OD: 102.5mm; ID: 47 mm ; Thickness: 31.5 mm the pipe size is 4 inch dia. Need to...

    Coefficient of friction of elastomer on steel

    I need to measure the co-efficient of friction of rubber (elastomer) seal on steel. How can I do this by experimentally ? I appreciate your any kinds of help regarding this issue. Thanks in advance.

    Stress at crack tip of a 2D cantilever beam under sinusoidal excitation

    I think the possible answer is principle stress in y-direction

    Stress at crack tip of a 2D cantilever beam under sinusoidal excitation

    I need some information urgently. I am working on crack of a 2-D cantilever beam. One side of the beam is fixed. I am applying a sinusoidal time varying load on other end in Y-direction.Beam length and width are 100cm and 10cm respectively. crack is 05 cm in y-direction. I have attached data and...
