Critical crack assessment procedure for high pressure steam turbine rotors
(Fatigue & Fracture of Engineering Materials & Structures, 1995)
Abstract A critical crack assessment procedure for high pressure steam turbine rotors is introduce and applied. The processes relating to low‐cycle thermal fatigue (LCTF), high‐cycle fatigue (HCF) and creep are considered ...
Application of two independent measurement techniques for determination of ductile crack growth initiation
(Springer Netherlands, 1999)
Charpy impact testing of the high strength low-alloyed steel has been performed by simultaneously recording two independent signals. The magnetic emission (ME) and potential drop (PD) techniques were used to determine ...
Evaluation of residual life of steam turbine rotors
(Mezhdunarodnaya Kniga, Moscow, Russian Federation, 1995)
A consideration is given to the problem of determining remaining operational life of steam turbine rotors at the following mechanisms of crack initiation and propagation: low-cycle thermal fatigue, high-cycle fatigue and ...
Determination of moist air drying ability using chemical potential of water vapour
(Taylor & Francis Inc, Philadelphia, 1998)
A thermodynamically simple method for calculation of chemical potential of water vapour, contained in the unsaturated moist air used as a drying medium in convective dryers, is developed. The introduced concept enables ...
Conservation law of J integral type for non-stationary time dependent fracture mechanics
(Kluwer Academic Publishers, 1994)
Mogućnosti i ograničenja za povećanje efikasnosti korišćenja energije u SRJ
(Savez energetičara Jugoslavije, Beograd, 1998)
Nepovoljni trend oporavka privrede, posle formalnog ukidanja sankcija uslovljen nedostatkom sopstvenog kapitala za pokretanje proizvodnih aktivnosti, i činjenice da osim 'lon aranžmana', jedini Programi za koje će moći da ...
An experimental investigation into the operational safety of a welded penstock by a fracture mechanics approach
(Fatigue & Fracture of Engineering Materials & Structures, 1995)
Abstract—Three different fracture mechanics approaches were applied to two full‐scale penstock model tests. The two models were produced, using a Sumiten 80P HSLA steel (minimum yield strength 700 MPa and minimum ultimate ...
Crack significance evaluation with special reference to welded structures
(Plenum Publ Corp, New York, 1996)
Fracture mechanics parameters (stress intensity factor K-I and its critical value K-Ic, crack opening displacement, and the contour J integral) are originally defined for static and quasistatic loading conditions. On the ...
Numerical and experimental investigation of cooling rates in a spherical casting
(FMJ Int Publications Ltd, Redhill, 1994)
Numerical and experimental investigation of cooling rates in spherical casting (rolling balls made of white alloyed iron) was performed. Temperature history was determined by measurement, using thermocouples (Pt-Pt/Rh), ...
Group theoretical formulation of nonsymmetrical systems by the group supermatrix procedure
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
The group supermatrix procedure, developed by Zlokovic for systems with symmetry properties described by groups, can be also applied to systems without symmetry. Transformation of a nonsymmetrical system into a system with ...
