LEFM to Investigate the Impact of Deteriorated Particles in Composite Material
Volume 14: Emerging Technologies; Safety Engineering and Risk Analysis; Materials: Genetics to Structures, 2015Due to its distinguished properties especially being isotropic, particulate reinforced composite is considered as one of the attractive material for wide range of applications, where the relatively low manufacturing cost is a desirable advantage. In the present analysis, deteriorated particles embedded in particulate reinforced composite have been ...

Pipe failure and lifetime using LEFM
2003A long pipe has an outer diameter (OD) of 90 mm, an inner diameter (ID) of 70 mm and works at a pressure (p) of 40 MPa. Valve failure downstream in the pipe caused a pressure surge which burst the pipe. Examination of the fracture surface revealed a metallurgical defect at the inner surface of the pipe which was semi-elliptical in shape with a depth of

Applicability of LEFM to Fatigue Crack Growth
2003Determine the limits from where the application of LEFM life models would result into a minimum error for 2024-T351 Aluminium alloy. The mechanical properties of the material are: Fatigue limit at R=0.1 is 220 MPa, the cyclic yield stress is 450 MPa and the grain size is 52µm.

Linear Elastic Fracture Mechanics (LEFM) and Applications
2001In brittle fracture it is assumed that failure in an elastic material takes place when the available elastic energy is adequate to overcome the energy necessary to propagate a crack and to create new crack surfaces. At the instant of instability, the stresses at the apex of an elastic crack must have sufficient magnitude, capable of driving the crack ...

Engineering Fracture Mechanics, 1996
Abstract A recently proposed comprehensive new approach that accurately explained and quantitatively predicted LEFM (long) Fatigue Crack Growth (FCG) behavior of metals and alloys in three stages, involved on a “general” or “phenomenological” level the combined roles of four interrelated variables, e.g.

New insights into crack analysis: general solution vs LEFM
Engineering Fracture Mechanics, 1998Abstract This paper examines the behaviour under tensile load of an elastic plate with a crack. Significance of the general solution of the problem is investigated. It is found that the crack opening parameters can be used as fracture parameters. It is shown that the first term in the power series expansion for any stress component of the general ...
