In connection with steel pipe concrete,it introduces mechanical action of calculating steel pipe concrete beam under different shock loadings by gigantic general limited meta calculating sofeware ANSYS and gets the deformational curves under shock loading at the time of stress changing and acceleration so as to offer references for knowing steel pipe concrete furtherly.
The strain history and damage evolvement of bearing material acted on by jet impact load can be calculated efficiently using the proposed method, which develops a new method of analyzing cavitation erosion failure of the bearing surface.
The available experimental results are used to find the dependence on the Mach number of the maximal impact drag coefficient and the growth time of the impact load when a disk enters a compressible fluid at an angle to the free surface.
The influence of compressibility on the duration of the rise time and the impact load was investigated experimentally in the range of Mach numbers 0 >amp;lt; M0 >amp;lt;-0.3 .
This paper presents equations for determining the peak impact load of a car crashing into a rigid concrete safety barrier.

Experimental and Calculation Analysis of the Behavior of Titanium Diboride-Boron Carbide Cermet under Impact Loading
A generalized mathematical model of the behavior of high-strength single-phase ceramics is proposed and analyzed by the example of titanium diboride TiB2, boron carbide B4C, and TiB2 + B4C cermet under impact loading.
Effect of anomalous melting points upon impact loading
It is shown that a high-rate shear of metals under explosive or impact loading may lead to generation of megagauss magnetic fields.
It is shown that taking this effect into account removes the discrepancy in determination of the dislocation dynamic damping coefficient by two methods, namely, with an electron beam and by mechanical impact loading.
The new model is used to obtain a numerical solution to the problem of the propagation of a plane wave produced by a shock load and the interaction of the wave with a fixed obstacle.
From results carried out, we have observed that there exists the dynamic stress-focusing phenomenon at the center of a solid sphere under shock load and it results in very high dynamic stress-peak.
Dynamic response of deformable structures subjected to shock load and cavitation reload
The dynamic response of deformable structures subjected to shock load and cavitation reload has been simulated using a multiphase model, which consists of an interface capturing method and a one-fluid cavitation model.
