An equation of the critical volume fraction, fpc, of particle-reinforcement in a composite, including particle size, yield strength of the matrix, dissipation work in the vicinity of the particles and the width of the interface zone, has been educed by the energy theory on the basis of the types of microscopic failure of the composite.

Effect of phosphorus on the yield strength of as-quenched GH761 alloy;

Study of influence factors of yield strength of oil and gas pipeline;

A modeling study of the yield strength of HRB335 hot rolled ribbed bar;

Based on the plain carbon steel with the chemical composition of 200MPa class steel the products of the yield stress of 400～500 MPa class and high-quality mechanical properties can be produced using the technology of chemistry tightly-tuning and controlled rolling - controlled cooling.

From the tests, a two-stage linear relation has been found between yield stress(σ_s) and strain rate(ε),σ_s=σ_0+klgε.

Yielding behavior of mismatched welded joint and prediction of its yielding strength;

Mechanical properties of normalized and tempered 12Cr2Mo steel forgings,primarily yielding strength,were on the low side.

In this paper numerical simulation was used on investigating the matrix yielding initiation and expansion of polymer blends which has a continuous single phase and a regular particles shape.
