According to the established empirical formula, the dynamic notch fracture toughness of the testing rock samples under split Hopkinson pressure bar (SHPB) impact loading condition are obtained from the dynamic strain signals in pressure bars. The experimental results reveal that the dynamic notch ...
The wind load formula was calculated as: $$F = \left( {0.5{\text{C}}_{d} \uprho A{\text{v}}^{{2}} } \right)\frac{9.80665}{{1000}}$$ (2) where, F is the force of the wind in the crown (kN); Cd is the drag coefficient stands for the flexibility that the palm or...

(36) Incentive stock option as an institutional arrangement has its important theoretical basis. (37) The orcin...
The paper presents a theoretical model for the normal contact of a rigid sphere with an elastic-perfectly plastic half-space or an elastic-perfectly plastic sphere with a rigid wall. Formulae describing the force-displacement relationship for static contact problems and the coefficient of restitution...
Based on the stress-strain characteristics of the broken rock mass in a goaf, an empirical formula for the correlation between stress recovery and land subsidence can be established, and this basically meets the exponential function relationship [15–17]. The stress-strain relationship of broken ...
By approximately calculating the average extrusion amount ahead of the cutterhead and utilizing the Kelvin problem solution in elastic mechanics, a formula was derived to calculate the additional stress between the cutterhead faceplate and the soil due to the extrusion effect. (3) Based on the ...

A novel temperature-dependent fracture strength model for ceramic materials is developed, based on a critical fracture energy density associated with material fracture comprising strain energy, the corresponding equivalent potential energy, and kinetic energy of atoms per unit volume. It relates the ...
We can calculate the mo- ment by formula (6) till ε t = ε tc or ε t-con =ε tu-con when Mcr the moment at the time first cracking occurs will be obtained. Hereafter, the beam comes into the service stage with cracks. Moment of beam section in service stage can be cal- ...
