The material force approach is an efficient, elegant, and accepted means to compute the J‐integral as a fracture mechanical parameter for elastic and inelastic materials. With the formulation of a multiplicative split of the deformation gradient at hand, rate‐dependent (visco‐elastic) materials described for example by the physically based Bergström‐Boyce model can be investigated. For these investigations, the so‐called material volume forces have to be computed in order to separate the driving forces acting on the visco‐elastic zone around the crack tip from the driving forces acting on the crack tip itself, representing the crack driving force. To illustrate the effectiveness of this approach, the so‐called dwell‐effect of elastomeric materials is investigated.

Fracture mechanical behaviour of visco-elastic materials: application to the so-called dwell-effect NAESER, Bastian; KALISKE, Michael; Dal, Hüsnü; NETZKER, Christiane (Wiley, 2009-08-01) The material force approach is an efficient, elegant, and accepted means to compute the J-integral as a fracture mechanical parameter for elastic and inelastic materials. With the formulation of a multiplicative split of the deformation gradient at hand, rate-dependent (visco-elastic) materials described for example by the physically based Bergstrom-Boyce model can be investigated.

Fracture analysis of welded connections Yetgin, Ali; Kadıoğlu, Fevzi Suat; Department of Mechanical Engineering (2013) The main objective of this thesis is to evaluate structural integrity of a multi barrel launcher system on fracture mechanics basis by using finite element method. A global finite element model that includes necessary kinematic and elastic connections is built. Dynamic firing forces are applied on global finite element model and general structural response is obtained. Sub modeling method is used in order to perform crack analysis. Since size of global model is too large to include solid crack elements whic...
Plane strain analytical solutions for a functionally graded elastic-plastic pressurized tube Eraslan, Ahmet Nedim (Elsevier BV, 2006-09-01) Plane strain analytical solutions to functionally graded elastic and elastic-plastic pressurized tube problems are obtained in the framework of small deformation theory. The modulus of elasticity and the uniaxial yield limit of the tube material are assumed to vary radially according to two parametric parabolic forms. The analytical plastic model is based on Tresca's yield criterion, its associated flow rule and ideally plastic material behaviour. Elastic, partially plastic and fully plastic stress states a...
Surface cracking in an orthotropic medium subjected to frictional contact Sarikaya, Duygu; Dağ, Serkan (2016-07-01) This article presents an analytical method capable of resolving the coupled problem of surface cracking in an orthotropic elastic medium subjected to frictional contact by a rigid flat punch. Reciprocal influences between the surface crack and the flat punch are accounted for by establishing a fully coupled formulation. Governing partial differential equations involving the displacement components are derived in accordance with plane theory of orthotropic elasticity. General solutions corresponding to mode ...
Separation at the interface of non-linearly elastic spinning tube-rigid shaft subjected to circumferential shear Akyüz, Uğurhan (Elsevier BV, 2004-10-01) Separation at the interface of homogeneous, isotropic, compressible, hyperelastic, spinning cylindrical tube-rigid shaft subjected to circumferential shear is investigated within the context of the finite elasticity theory. The compressible, hyperelastic spinning tube with a uniform wall thickness is assumed to be tautly fitted to a rigid shaft along its inner curved surface. The outer surface of the tube is subjected to a constant uniformly distributed circumferential shearing stress while the rigid shaft ...
