Approximate techniques for predicting size effects on cleavage fracture toughness (Jc) by Mark Kirk( Book )

2 editions published in 1993 in English and held by 87 WorldCat member libraries worldwide

This investigation examines the ability of an elastic T-stress coupled with a modified boundary layer (MBL) solution to predict stresses ahead of a crack tip in a variety of planar geometries. The approximate stresses are used as input to estimate the effective driving force for cleavage fracture (JO) using the micromechanically based approached introduced by Dodds and Anderson. Finite element analyses for a wide variety of planar cracked geometries are conducted which have elastic biaxiality parameters (B) ranging from -0.99 (very low constraint) to +2.96 (very high constraint). The magnitude and sign of B indicate the rate at which crack-tip constraint changes with increasing applied load. All results pertain to a moderately strain hardening material (strain hardening exponent(n) of 10). These analyses suggest that B is an effective indicator of both the accuracy of T-MBL estimates of Jo and of applicability limits on evolving fracture analysis methodologies (i.e. T-MBL, J-Q, and JIJO). .

J and CTOD estimation equations for shallow cracks in single edge notch bend specimens by Mark Kirk( Book )

2 editions published in 1993 in English and held by 87 WorldCat member libraries worldwide

Results from two dimensional plane strain finite-element analyses are used to develop J and CTOD estimation strategies appropriate for application to both shallow and deep crack SE(B) specimens. Crack depth to specimen width (a/W) ratios between 0.05 and 0.70 are modelled using Ramberg-Osgood strain hardening exponents (n) between 4 and 50. The estimation formulas divide J and CTOD into small scale yielding (SSY) and large scale yielding (LSY) components. For each case, the SSY components is determined by the linear elastic stress intensity factor, K sub I. The formulas differ in evaluation of the LSY component. The techniques considered include: estimating J or CTOD from plastic work based on load line displacement (A sub pl/ILLD), from plastic work based on crack mouth opening displacement (A sub pl/CMODpl), and from the plastic component of crack mouth opening displacement (CMOd pl). A sub plCMOD provides the most accurate J estimation possible. CTOD estimates based on scalar proportionality of CTOD sub 1sy and CMOD pl are highly inaccurate, especially for materials with considerable strain hardening, where errors up to 38% occur

Size and deformation limits to maintain constraint in KIc and Jc testing of bend specimens by Kyle C Koppenhoefer( Book )

2 editions published in 1995 in English and held by 85 WorldCat member libraries worldwide

The ASTM Standard Test Method for Plane-Strain Fracture Toughness of Metallic Materials (E399-83) restricts test specimen dimensions to insure the measurement of highly constrained fracture toughness values (K sub Ic). These requirements insure small-scale yielding conditions at fracture, and thereby the validity of linear elastic fracture mechanics. When these conditions are satisfied, the diameter of the plastic zone is nearly twenty five times smaller than all specimen dimensions. The need for this degree of plastic zone confinement, set by the factor 2.5 in a, b, B greater than or equal to 2.5(K sub q/omega sub ys)squared was based on K sub Ic data for many different alloys. These data show that all specimens satisfying the size requirements of E399 produce highly constrained fracture toughness values. However, the required multiplier ranges from 1.0 for certain steel alloys to 2.5 for titanium alloy 6- 6-2 in the aged condition. To maintain a standard test method applicable to all materials, the more restrictive 2.5 value has been retained by ASTM Committee E08. Recently, Dodds and Anderson have proposed a less restrictive size requirement for cleavage fracture toughness measured in terms of the J-integral (J sub c). Dodds and Anderson performed finite element analyses to calculate the ratio of J in the finite-sized specimen (J sub SE(B)) to J under small-scale yielding (J sub SSY) needed to produce equivalent stresses ahead of both crack tips, and thereby equivalent conditions for cleavage fracture.

Improving subdrainage and shoulders of existing pavements by Barry J Dempsey( Book )

3 editions published in 1982 in English and held by 73 WorldCat member libraries worldwide

Laboratory, test track and field results on channeling and pumping are presented. The influence of water on pumping and erosion of fine material from beneath the pavement surface is clearly shown. Methods for pavement drainage design in expansive soils and to resist the effects of frost action are presented. It is shown that the depth and location of subdrain systems will influence the water flux. Equipment and procedures for the maintenance and cleaning of subdrain pipes are discussed. A hydraulic jet unit for cleaning pipe subdrains has been discussed in detail

2 editions published in 1982 in English and held by 68 WorldCat member libraries worldwide

This state-of-the-art report reviews the existing literature and current practices relating to subdrainage, shoulder structures, and maintenance of existing pavement systems. Methods for classifying the various types of pavement subdrainage are presented. Problems related to subdrainage are discussed in detail. The flow equations which describe saturated and unsaturated water movement in pavement materials and subgrades are discussed. Procedures presently being used for subdrainage design and construction have been presented. The function, problems and design of pavement shoulders have been described in detail. Examples of shoulder designs used by several States are presented. Maintenance practices affecting shoulder performance and mositure related distress are presented. A number of maintenance practices presently being used to decrease the effects of moisture on pavement distress are thoroughly discussed
