They also put forward that bolted joints as virtual materials which have equal cross section, then base on engineering data parameters to set up dynamic model.
Su Tiexiong [48] determined the nature of the specific materials through the results of modal experiment in 2001.
Tian Hongliang [39] in 2011 put forward a kind of dynamic parametric modeling method based on virtual material, which was that regarded the bolted joints as a cross section of the virtual material, then thought that joint part unit was equivalent to a fixed connection of virtual materials and binding surface of two parts, and base on engineering data parameters to set up dynamic model and solve the problem of the dynamics model of engineering practicability.

Titanium and its alloys are notorious for their poor thermal properties and are classified as difficult-to-machine materials.
However, titanium alloys are regarded as extremely difficult to cut materials.

Modelling of microstructure evolution during thermal processes – a hybrid deterministic-probabilistic approach Iraj Hadi1, a, Mohammad-Amin Jabbareh1, b, Roghayeh Nikbakht1, c and Hamid Assadi1, d 1 Tarbiat Modares University, Dept. of Materials Engineering, P.O.
Introduction Numerical modelling has for decades served as a robust and feasible tool for the study of various materials processes.
Originally used to simulate solidification processing of materials [1], phase-field approach has been extended to model a spectrum of processes, ranging from sintering [2] to electrochemical reduction of oxides [3].
Numerical simulations were carried out for four cases of materials processes as described next.
Laser is widely used for cutting, welding and surface modification of metallic materials.

Ceramics based on materials with perovskite structure are very significant electronic ceramic materials.
This material as also a key component for a synthetic rock form used to immobilize nuclear waste [7].
Recently, mechanochemical synthesis has been successfully used to synthesize materials, such as nano-crystalline oxide powders, solid solutions and various functional materials, such as perovskite ferroelectrics [14-17].
