Effect of remaining ligament on fatigue crack growth
نویسندگان
چکیده
Fatigue crack growth (FCG) has been studied assuming that ∆Keff is the driving force. However, effect of ligament on FCG rate not clear. Experimental-numerical work was developed in 18Ni300 maraging steel considering different load blocks with same initial ∆K. No observed experimentally, which explained by inexistence closure effects. In numerical transient effects were for plane stress state, disappear strain state and some found. both cases this attributed to phenomenon.

Accelerated Threshold Fatigue Crack Growth Effect – Powder Metallurgy Aluminum Alloy
Fatigue crack growth (FCG) research conducted in the near threshold regime has identified a room temperature creep crack growth damage mechanism for a fine grain powder metallurgy (PM) aluminum alloy (8009). At very low ∆K, an abrupt acceleration in room temperature FCG rate occurs at high stress ratio (R = Kmin/Kmax). The near threshold accelerated FCG rates are exacerbated by increased levels...
متن کاملA cohesive model of fatigue crack growth
We investigate the use of cohesive theories of fracture, in conjunction with the explicit resolution of the near-tip plastic fields and the enforcement of closure as a contact constraint, for the purpose of fatiguelife prediction. An important characteristic of the cohesive laws considered here is that they exhibit unloadingreloading hysteresis. This feature has the important consequence of pre...
متن کاملThermo-Mechanical Fatigue Crack Growth of RR1000
Non-isothermal conditions during flight cycles have long led to the requirement for thermo-mechanical fatigue (TMF) evaluation of aerospace materials. However, the increased temperatures within the gas turbine engine have meant that the requirements for TMF testing now extend to disc alloys along with blade materials. As such, fatigue crack growth rates are required to be evaluated under non-is...
متن کاملStochastic Analysis of Fatigue Crack Growth
Due to cost and time limitations, experiments for fatigue crack growth are only feasible below certain cycle numbers. In this paper, it is investigated whether or not fatigue crack growth laws allow for an extrapolation of the statistics of the cycle number to reach a certain crack length from limited experimental data, and hence reduce costs.
متن کاملOn Crack Closure and Crack Tip Shielding during Fatigue Crack Growth
Fatigue crack growth can be strongly influenced by crack closure, i. e., the contacting of the opposing faces of a fatigue crack above the minimum load in a loading cycle. This crack closure shields the crack tip from the full stress field, but different views are held regarding the extent of this shielding. The type of closure, whether it be plasticity-induced, or roughness-induced may also pl...
