Non‐linear fracture mechanics and finite elements

T.K. Hellen, W.S. Blackburn

A review is made of methods for calculating parameters characterizing crack tip behaviour in non‐linear materials. Convenient methods of calculating J‐integral type quantities are…

Three discrete Kirchhoff elements for shell analysis with large geometrical non‐linearities and bifurcations

M. Talbot, G. Dhatt

The comparative efficiency of three flat triangular shell elements is being assessed for analysing non‐linear behaviour of general shell structures. The bending formulation of the…

Prediction of the flow, reaction and heat transfer in an oxy‐fuel glass furnace

M.G.M.S. Carvalho, D.F.G. Durão, J.C.F. Pereira

A three‐dimensional computer simulation of a combustion chamber used in the glass production industry is presented. A numerical solution technique is used to solve the governing…

A symmetric formulation in non‐associated viscoplasticity

M.H.F. Melão Barros†, R.A.F. Martins, L.M.J.S. Dinis

Implicit solutions in viscoplastic analysis of structures are very often avoided due to the fact that they lead to non‐symmetric systems of equations. On the other hand…

Non‐linear analysis of plate and folded plate structures by the finite strip method

Miodrag Sekulovi, Dragan Milašinovi

An analysis of the plate and folded plate structures is carried out, taking into account the geometrical non‐linearities and the effects of creep, using the finite strip method…

Numerical analysis of dynamic quasi‐bifurcation

M. Kleiber, W. Kotula, M. Saran

A simple finite element approach to problems of dynamic structural instability under step loading is discussed. The method proposed is believed to yield important information…

A generalized mixed time integration program for structural dynamics

J.P. Coyette

The numerical treatment of coupled field interaction problems frequently uses mixed time integration methods. These methods permit different time integration methods (implicit…

Application of the finite strip method to the thermal analysis of engineering structures

Zbigniew Mańko

While calculating internal forces of a structure resulting from temperature it is necessary to know thermal conduction and what goes hand in hand to determine temperature…

Influence of shear deformation in a composite equilibrium element for the analysis of thin plates

E.A.W. Maunder

A composite triangular equilibrium element for modelling thin plate behaviour is investigated when shear deformation, according to Reissner's theory, is included in addition to…
