Commercial finite element software follow cautiously the numerical methods developed by scientific community. Even though phase-field method is not a default option in Abaqus, code proposes unique way to implement and test complex, extraneous models. In last five years, fracture models Abaqus have gained unbelievable popularity among scientists engineers alike. However, most implementations are...

since the emergence of the process-oriented approach to second language writing instruction two main questions have been what and how error feedback should be given to the students. the question of whether teachers should provide feedback on grammar in the writing assignments of english as a foreign language students, and if so how, has been a matter of considerable debate in the field of secon...

Synthetic fibre reinforcements are increasingly replaced with plant fibres but an improvement in the mechanical performance of biocomposites is required. Flax composite exhibits failure and perforation even at low impact energies. This paper investigates viability improving resistance flax-epoxy biocomposite by hybridisation a thin metal layer. High-speed cameras optical microscopy were used to...

In machining, tool/workpiece interface parameters are complicated to estimate by experimental means alone. Numerical methods can then give critical solutions predict and analyze the influencing machining. The friction between tool cutter has a direct influence on milling parameters. Therefore, it is necessary understand mechanism workpiece of Nomex honeycomb structures correctly. This work aims...

Abstract Magnesium alloys, because of their good specific material strength, can be considered attractive by different industry fields, as the aerospace and automotive one. However, use is limited poor formability at room temperature. In this research, a numerical approach proposed in order to determine an analytical expression hot incremental forming processes. The model was developed using co...
