Threedimensional transient analysis of a submerged cylindrical shell is presented. Threedimensional trilinear eightnoded isoparametric fluid element with pressure variable as unknown is coupled to a ninenoded degenerate shell element. Staggered solution scheme is shown to be very effective for...
The paper considers a plane joint or interface element suitable for implementation into a standard nonlinear finite element code. Sliding of the joint is assumed to be governed by Coulomb friction, with a nonassociated flow rule and no cohesion. The constitutive equations are formulated in a...
An exact multiplelevel dynamic substructure technique was developed by a combination of WYD algorithm and static multiplelevel substructuring technique. This method is essentially different from the traditional mode component synthesis. The eigenvalues and eigenvectors created by the method are...
A technique for computing free surfaces by a steady state approach has been included in the hot rolling code ROLL3. It has been described in a previous paper, along with applications to some simple rolling passes. In the present text, new developments are included to deal with more complex...
Based on the orthogonal approach for hybrid element methods, refined threedimensional isoparametric hybrid hexahedral elements have been developed. The behaviour of the proposed models are discussed in respect of coordinate invariance, spurious zero energy modes and the ability to pass the patch...
An analysis model has been developed for the elastoviscoplastic analysis of continuous fibrereinforced composite structures. Elastic deformation of fibre and elastoviscoplastic deformation of matrix are considered in the analysis model because the yield strength of matrix is, in general,...
