A GENERALIZED PHASE-FIELD APPROACH FOR THE FAILURE OF RUBBER-LIKE MATERIALS
Açıkgöz, Kemal; Dal, Hüsnü; Department of Mechanical Engineering (2023-2-13)
Dilatational failure in terms of cavity formation and distortional failure guided by shear-type deformations are the two main failure modes of rubbery polymers. These modes correspond to deformations associated with the energetic/volumetric and entropic/shear responses under general loading conditions. This work proposes an energy-based failure criterion with a unique split of the free-energy function in terms of the first three invariants. Such an ansatz allows various failure modes under volumetric and sh...

A nonlinear equivalent frame model for displacement based analysis of unreinforced brick masonry buildings
Demirel, İsmail Ozan; Sucuoğlu, Haluk; Department of Civil Engineering (2010)
Although performance based assessment procedures are mainly developed for reinforced concrete and steel buildings, URM buildings occupy significant portion of building stock in earthquake prone areas of the world as well as in Turkey. Variability of material properties, non-engineered nature of the construction and difficulties in structural analysis of perforated walls make analysis of URM buildings challenging. Despite sophisticated finite element models satisfy the modeling requirements, extensive experi...
A modulus gradient model for inhomogeneous materials with isotropic linear elastic constituents
Gülaşık, Hasan; Göktepe, Serdar; Gürses, Ercan (Elsevier BV, 2019-11-01)
The one-dimensional modulus gradient (E-grad) model proposed in Gülaşık et al. (2018) is extended to more general three-dimensional inhomogeneous materials with isotropic linear elastic constituents. In addition to the constitutive equations and balance relations, length scale dependent differential relations for the material parameters of isotropic linear elasticity are provided. The finite element formulation for axisymmetric problems is derived and a model problem of a soft cylindrical rod with a stiff s...
A layerwise approach to modeling piezolaminated plates
Ertürk, Cevher Levent; Tekinalp, Ozan; Department of Aerospace Engineering (2005)
In this thesis, optimal placement of adhesively bonded piezoelectric patches on laminated plates and the determination of geometry of the bonding area to maximize actuation effect are studied. A new finite element model, in which each layer is considered to be a separate plate, is developed. The adhesive layer is modeled as a distributed spring system. In this way, relative transverse normal and shear motion of the layers are allowed. Effect of delamination on the adhesive layer stresses is also studied and...
