Crack tip opening displacement in a linear strain hardening material

Mechanics of Materials, 2013
Abstract For a linear strain hardening material, we investigate the strain hardening effect on the crack tip opening displacement (CTOD) and obtain some interesting results. The nonlinear constitutive equation is simplified into a valid form, and a hardening function is introduced to solve this problem analytically.

Critical crack tip opening displacement for polymer composites

Engineering Fracture Mechanics, 1989
Abstract Applicability of critical stress intensity factor ( K IC ) and/or critical crack up opening displacement (CTODc for epoxy and polyester polymer composites (PC) in mode I Fracture are investigated. Both unreinforced and glass fiber reinforced polymer composite systems are studied using single edge notched beams in three-point and ...

The effect of shallow cracks on crack tip opening displacement

Engineering Fracture Mechanics, 1986
Abstract Further results given in the present paper confirm that shallow cracks have larger crack tip opening displacements at initiation than deep cracks. This difference in behaviour is shown to be principally caused by the different hydrostatic stresses existing at the tips of shallow and deep cracks.

Crack Tip Opening Displacement of X100 SAWL Pipe

Advanced Materials Research, 2011
The fracture toughness of different zones of X100 SAWL pipe was studied by three-point bend test method under different temperature. At the same temperature, the crack propagation resistance and tear modulus of X100 SAWL pipe distributed as: base metal>HAZ>weld bead, and the distribution of the CTOD value of X100 SAWL pipe is :base metal >weld

Fatigue crack propagation under programmed loads and crack tip opening displacements

Engineering Fracture Mechanics, 1970
Abstract A fatigue crack propagation model relating fatigue crack growth rates to crack tip opening displacements is evaluated in the case of two tests under programmed loads with a peak overload every 200 cycles. It is shown that the relative amount of crack extension produced by different load amplitudes can be related to the relative crack tip ...

Dynamic Measurement of Crack-Tip Opening Displacement

1988
Crack opening displacements were measured at two positions very close to the tip of a crack in three-point bend specimens that were loaded explosively. Indentations were placed across the fatigue precrack at locations 100 μm and 200 μm behind the tip. These indentations, when illuminated with a laser, generate fringe patterns in space, and the motion ...

On the cyclic crack‐tip opening displacement

Fatigue & Fracture of Engineering Materials & Structures, 2009
ABSTRACTThis note discusses the cyclic crack tip opening displacement (CTOD)cyc. As is discussed, the correct expression for the (CTOD)cycis based upon the effective range of the stress intensity factor.

Relationship between notch tip strain and crack-opening displacement

Materials Science and Engineering, 1980
Abstract A model is proposed for strain associated with smooth blunting of a notch under mode I type of loading. The model yields a relationship between notch tip strain and crack-opening displacement. The predictions of the model were found to be in good agreement with Robinsons and Tetelman's experimental data on A533-B steel.

Critical Crack-Tip Opening Displacement of SCLC

2018
The aim of this study is to consider the effects of water/binder ratio on fracture behavior of self-compacting lightweight concrete (SCLC). To do so, four mixes with constant nominal size of aggregate (d a = 12.5 mm) have been prepared such that the weight of aggregate and portion of coarse aggregate to fine aggregate were designed to be constant ...

Critical crack tip opening displacement of different strength concrete

Journal of Central South University, 2011
Critical crack tip opening displacement (CTOD(subscript c)) of concrete using experimental and analytical evaluation with seven different compressive strengths ranging from 30 up to 150 MPa was studied based on two types of fracture tests: three-point bending (TPB) and wedge splitting (WS).
