Computational modelling of thermal impact welded PEEK/steel single lap tensile specimens
In this contribution, an interfacial traction-separation-law based on elastoplasticity with Lemaitre-type-damage is applied. Related constitutive equations are decoupled with respect to a local orthonormal frame such that the stress–strain response is controlled independently in these directions. The constitutive traction-separation-law is applied to the simulation of thermal impact welded (TIW...
متن کاملNumerical Analysis of the Shape Effect on the Tensile Strength Evaluation of Axisymmetric Specimens
This paper analyses the shape effect on the tensile strength of axisymmetric rock specimens by an improved adaptive dynamic relaxation method. It is shown that the present approach is convenient and &cient. Numerical results for spheroidal specimens with different shapes reveal the variation of stress distributions along the loading axes and suggest that loading along the shorter principal axis...
متن کاملCritical Strain Energy Density from Tensile Specimens
Fracture has always been a serious concern in the design and repair of steel structures such as ships. Because of these concerns, much research has been ongoing in the causes of fractures and in ways which they could be predicted and thus prevented. The objective of this study was to flnd, test and evaluate a method for measuring tht:: critical strain energy density with tensile specimens. Plas...
متن کاملInvestigation of Tensile Properties of Bulk and Slm Fabricated 304l Stainless Steel Using Various Gage Length Specimens
The complex solidification dynamics and thermal cycling during Selective Laser Melting process is expected to result in non-equilibrium material characteristics. There is an essential need for characterization techniques which are critical towards the estimation of anisotropies. The current investigation is targeted towards establishing tensile testing methodologies and their relation to differ...
متن کاملTensile Testing of Carbon Steel in High Pressure Hydrogen
An infrastructure of new and existing pipelines and systems will be required to carry and to deliver hydrogen as an alternative energy source under the hydrogen economy. Carbon and low alloy steels of moderate strength are currently used in hydrogen delivery systems as well as in the existing natural gas systems. It is critical to understand the material response of these standard pipeline mate...
