Fracture toughness of the weld joints of the maraging steel rocket motor case obtained from
the limited Compact Tension (CT) specimens are found to be invalid due to the measured …

In this work, a hybridization technique is proposed. It consists of using two weight functions
to model elliptical cracks for computation of the stress intensity factor 'SIF'in mode I. The idea …

Aluminium has been the dominant material in the aircraft industry for a half century due to its
attractive combination of light weight, strength, ductility, corrosion resistance, ease of …

5 PH stainless steel is a martensitic precipitation-hardenable stainless steel (0.07 C-15Cr-
5Ni-3.5 Cu-Fe). Presently, high strength low alloy steel, AFNOR 15CDV6 is used for the …

This article highlights briefly the reported failure of critical parts and equipment in gas
turbine, heat recovery steam generator, and steam turbine, in addition to the requirements of …

A hybrid weight-function technique is presented. It consists of dividing an elliptical crack into
two zones, then using the appropriate weight function in the area where it is more efficient …

Fracture data of both parent metal and weldment metals from surface cracked tensile plates
made of 2219-T87 Al alloy at cryogenic temperatures were correlated using a modified …

The part-through fracture toughness (K Ie) and crack-tip opening displacement (CTOD, δ m)
of welded joints of aluminum alloy (AA) 20l4-T6, including the weld metal, the fusion zone …

In oil and gas pipelines, cracks can initiate from regions of high stress concentration or from
defects due to either manufacturing or corrosion or both. The cracks under service may grow …

Aluminum alloy AA2219-T852 tubular specimens were subjected to biaxial testing. The
specimens were tested under tensile as well as internal pressure simultaneously to create …
