Application of Caquot's solution to the analysis of stability of shallow circular cavities in Tresca material
… constitutive model assumed for the ground is the Tresca shear failure criterion. This material model is a particular case of the Mohr-Coulomb material model with zero internal friction angle and cohesive strength only. Closed-form solutions for computation of factor of safety under dry and …

A study of brittle powder compaction using a combined discrete finite element approach
… Mode II failure models used are the Rankine and Tresca failure models, respectively. The development of a pre-processor to generate the initial configuration of the particle assembly also formed a major component of the thesis. Algorithms to fill a plane with randomly shaped polygons were …

Fatigue limit analysis involving biaxial stress components
… concerning the Distortional Energy and Tresca criteria and how they are incorporated in fatigue design procedures. The work is restricted to cases in which the alternating principal stress axes have fixed orientation.

Time integration schemes for piecewise linear plasticity
… rule and isotropic material behavior. Both the Tresca and Mohr-Coulomb yield surfaces with perfectly plastic and linear hardening rules are considered in detail. The algorithm has the advantage of being fully linked to the governing principles and avoids the inherent problems associated with …

On a Proposal for a Continuum With Microstructure
… The capability of the model to predict not only Tresca and Von-Mises plastic behavior but also phenomena such as Prager's kinematic hardening, different responses in tension and compression, latent hardening, and the Bauschinger effect, is shown. Finally, the appropriateness of our equations to …

Métodos numéricos en elastoplasticidad
… de fluencia multisuperficies eikonales (Tresca). Para comprobar la eficacia de las nuevas fórmulas propuestas para el cálculo de la matriz tangente consistente, se ha desarrollado un código de elementos finitos que ha permitido comparar los resultados con los obtenidos por otros autores. …

A finite strain theory of elastoplasticity and its application to wave propagation
… elastic law, and with either the von Mises or Tresca yield criteria.

Finite element simulation of Durelli's photoelastic stress minimization method for shape optimization
… boundary become isochromatics of the same Tresca stress. The process of material removal was simulated by iterative deleting of elements lying on the stress raiser boundary, followed by smoothing and remeshing subroutines. The criterion proposed for element "removal" was to select only a …

Probabilistic analysis of the plastic collapse of random media
… randomly varying yield strength. Both the Tresca and Mohr-Coulomb yield criteria are considered in the present study. The two probabilistic methods developed are based on the upper and lower bound theorems of plastic limit analysis. By extending these two theorems to probabilistic cases the …

Crack path selection in microstructurally tailored inhomogeneous polymers
… of high stress levels using the von Mises and Tresca yield criteria. These criteria illustrate areas in which high magnitudes of stress occur and these results are compared with the experimental failure initiation sites.

Influence of large deformations and midplane forces on the plastic behavior of impulsively loaded plates
… linear radial displacement terms. Finally, the Tresca yield criteria are used. An interaction equation is derived between the plastic moment and normal force. The relationship indicates that the greater the midplane force the smaller the required bending moment for plastic flow. When the …

Sviluppo e calibrazione di modelli di danneggiamento plastico duttile in acciai strutturali per tubi da pipeline per il trasporto di gas e petrolio
… nel corso degli ultimi secoli (Coulomb, Rankine, Tresca, Von Mises, Mohr, Caquot...), solo di recente ci si è cominciati a preoccupare degli effetti del progressivo deterioramento dei materiali che ne precede la rottura. Solamente nel 1958 Katchanov pubblicava la sua prima memoria che coniava una …

Implementation of an anisotropic plasticity model and its application to pile foundations problems
… foundations, compared to the Modified Cam Clay, Tresca, and plasticity-based solutions. SANICLAY also provided quite lower lateral bearing capacities for pile groups and piled raft problems, compared to those obtained by an isotropic modified Cam Clay, although the two analyses displayed the same …
