Wood has many positive properties, but it's no secret that faced with its shortcomings such as fragility, instability of form and susceptibility to decay, people often prefer synthetic materials, putting aside the ecology and useful properties of wood and choosing the long life of non-natural materials.
So, the samples processed in oil were the most resistant of all materials due to the additional impregnation of wood with the treatment agent.

Soft magnetic powder cores are materials manufactured by pressing pure iron powder covered with insulating film into shape.
The issues to be addressed with regard to this kind of method are: (1) the pure iron used in these materials displays ductility resulting in burring and cohesion to machining tools, (2) these materials are green compacts with low binding forces between powder particles and high tendencies towards cracking and gouging, and (3) these materials possess residual pores at levels of several percent thus resulting in microscopically intermittent processing which causes heavy machining tool wear.
Soft magnetic powder cores (SMPCs) have gathered attention in recent years as materials for the iron cores described above [1].
These materials are produced by pressing pure iron powder covered with insulating film into shape.

Calculation on Fracture Parameter of Model I Crack Tip Based on ANSYS Ke Songa, Bangcheng Yangb Dept of Engineering Mechanics, Faculty of Civil Engineering and Mechanics, Kunming University of Science and Technology, Kunming 650500, China asongkesk@sina.com, byangbc5@163.com Keywords: interaction integral method, VCCT, fracture parameter, crack, ANSYS.
The fracture parameter can only be applied in the elastic material.
When crack produce enough energy to overcome the material resistance stress, it will have the crack propagation.
But altering the material parameters of the crack model will not change stress intensity factor and the energy release rate.
