Tensile Strength

11/10/2017 6:59 AM

I need to calculate the tensile strength of PE sheet insulation in Kpa of Size 1m x 2m with 10mm thickness. Density of the insulation 125 Kg/M3.

Tensile strength is given as 23.2 Kg/cm2 (Longitudinal) & 16.8 Kg/cm2 (CrossWise).

Can someone help in calculating the Tensile strength in Kpa.

1 PSI equals 6.895 Pascals.

1 kg/cm2 equals 98,066.5 Pascals.

Do you mean to say that 1 kg/cm2 equates to 98.07 kPa? Why, I believe you do.

23.2 kg/cm2 converts to about 2275.1 kPa, using that proportionality.

16.8 => 1647.5 kPa.

You can't calculate it.

You can convert it.

I'm curious to know what you think you will learn from this meaningless conversion?

Also, I'm interested to know if you are aware of the reason for the difference in strength of the two directions.

Near enough for practical purposes, 1bar = 1kg/cm2 and kPa = 100*bar. If you want more accuracy see JS #2.

And it's kPa, not Kpa. XL (for example) has an irritating habit of "correcting" MPa to Mpa, but if you insist it leaves it alone.
