By obtaining the data of BR1500 HS isothermal tensile test, it established a "" shaped part of thermal-mechanical coupled model which is based on ABAQUS to analyze the influences of forming speed and holding time on the forming properties.
From the hot stamping process, the key factors affecting hot stamping performance are how to determine the appropriate speed and holding time.
Therefore, the study of these two key factors has important practical significance for the development of the hot forming process.
Because steel material mechanical properties are insensitive to the direction of rolling, the test does not involve that.

The mechanical properties of plywood decreased more severely after accelerated aging test in acidic condition.
However, the influence of different curing catalyst contents on mechanical properties and formaldehyde emission of UF resin can be minimized by adding melamine to the resin.
The ingress of moisture could significantly decrease the strength properties[4], while hydrolysis of cured UF resin was a major factor affecting formaldehyde emission[5].
The experiment results showed that the durable mechanical properties of plywood were relational to the initial properties of UF resin but not the melamine contents, formaldehyde emission after accelerated aging test increased significantly and irregularly.
However, the influence of different curing catalyst contents on mechanical properties and formaldehyde emission of UF resin can be minimized by adding melamine to the resin.

The results show that: the unloading process is an important factor affecting the structural vibration; Displacement peak and open grab time are inversely proportional; Increase the open grab time can reduce the vibration of the structure.
Wang Shu-Zhen (2009) and some other researchers showed that lifting process influence is an important factor of the crane structure vibration [1-4].
He Cheng-Zhong (2010) in the paper pointed out that under portal crane with Self-Funnel unloading process, funnel had the dynamic load impact, the impact would bring crane structure vibration sharply, the crane stress response and displacement response would be peak, unloading process was also an important factor affecting the structural vibration [6].Structural vibration can destroy some sensitive components of the portal crane with self-funnel, so the research of the dynamics analysis under unloading process has important theoretical value and engineering application value.
(2)The bulk impact the funnel is one of the main factors to affect the structure dynamic characteristics, the structure vibration is intense, the displacement changes particularly fast

Effects of beetle attack on the bending and compression strength properties of pine wood Helena Cruz1, a, José S.
Its effects may generally be considered, either by assuming a reduced cross section or by assuming reduced mechanical properties for the apparent cross section.
Therefore, its effects need be considered [1], either by assuming a reduced cross section or by assuming reduced mechanical properties for the apparent cross section [2].
Taking into account the damage pattern, it seems more logic to assume reduced mechanical properties in proportion to the “diffuse” loss of material, therefore in proportion to the loss of density.

Corrosion Behavior of Rebar HPB235 in NaCl Solution Ying Wang 1, a 1Department of Civil Engineering, Luoyang Institute of Science and Technology, Luoyang 471023, China aeappol@163.com Key Words: Rebar HPB235, Corrosion behavior, Corrosion rate, Mechanical properties Abstract: The corrosion behavior of rebar HPB235 in 1.5wt.% NaCl solution was studied and its mechanical properties were tested before and after corrosion.
The corrosion of rebar is one of the main factors to affect the duration of concrete structure, which has attracted people’s extensive attention.
There are two important factors to cause the corrosion of rebar [1-3]: one is carbonization of concrete, and the other is inrush of chloride.
The self quality of concrete structure is also one of the main factors to cause the corrosion of rebar.
The mechanical properties, including yield strength, tensile strength and elongation, are tested by a hydraulic pressure universal testing machine.
