Other factors that impact the tensile strength values of plastics Velocity of testing, Orientation level of fibers, Temperature, Filler content, etc. What are the test methods to measure tensile properties of plastics? In general, “tensile test methods” measure the modulus of elasticity of mater...
This paper mainly focuses on the cracking problem of concrete structures, researches on the biaxial tensile strength of cement concrete. The biaxial tensile instrument is used for material test, the biaxial tensile strength formula is proposed, and the theoretic formula is deduced by Hill criterion....
The tensile strength Rm is calculated by the formula: Rm=FmaxS0,MPa where: Fmax - maximum force (load required to break the sample) [N], S0 - initial area of the measuring part of the test sample [mm2]. Young׳s modulus of elasticity E represents the ratio between stress σ and str...
So, the point at which the cloth can stretch and start tearing up later is called the tensile strength of the cloth. Solids are more tensile and withstand more tensile strength than gases as the gases are free particles and solids are more compacted, the solids have more capacity to stretch...
the equivalent stress σG at the center point of the face plate is 1.62 times greater than its internal center one.In determining the rock tensile strength according to the usual formula,it is recommended that the disc thickness is 0.3 times smaller than the disc diameter.By doing so,the ...

THE FORMULA FOR COMPUTING THE TENSILE STRENGTH OF CONCRETE FOR THE SPLIT CYLINDER TEST WAS FIRST DERIVED USING THE THEORY OF LINEAR ELASTICITY. AN IDENTICAL FORMULA WAS DERIVED RECENTLY USING THE THEORY OF PERFECT PLASTICITY. AS A RESULT, A NEW TENSION TEST, THE DOUBLE-PUNCH TEST, WAS PROPOSED...

The splitting tensile test, also known as indirect tensile strength test, captures the peak compressive load applied transversely to a cylindrical specimen prior to or on the onset of cracking, and therefore does not necessarily reflect the material's post-peak behaviour. ...
