牛的細微差別

Time Effects and their Influences on Test Procedures for Measuring Dynamic Material Strength Valuesors are measured under specific conditions, for example at the beginning of yield, at the onset of rapid fracture, etc. These mechanical quantities in general are also not measured directly, but electronic signals from strain gages as parts of different measuring devices are recorded.

Nonlinear and Dynamic Fracture of Cracked Structures under Electromagnetic Forceructure which carries a transient electric current . and is placed in an uniform and steady magnetic field .. In the numerical analyses, we calculate the electric current distribution, the Joule heating and the extended J-integral with the effect of the electromagnetic force on fracture phenomena by

Size Effects in Solid Mechanics Due to Topology Transformation during Crack Growtheory as crack growth criterion. An elastic-softening constitutive law is considered and the damage of the material is obtained by decreasing elastic modulus and fracture toughness in relation to the strain energy density absorbed in the volume element. In this way, the strain energy density factor S

Ductile Fracture Propagation Studies by a Kinematic Approachn angle 2θ, crack tip opening angle CTOA, crack length a and fracture profile coordinates. A methodology is proposed for measuring the R-curve in terms of CTOA, starting from only geometric information, taken either during the test, i. e., θ = θ(a), or from broken test-pieces profiles.
