In order to study influence of the filling material on the lateral effect of penetrator with enhanced lateral effect(PELE), three dimensional numerical simulation of PELE impacting target was carried out,and the PELE is loaded with distinct filling material.

Penetrator with Enhanced Lateral Effect (PELE) is a kind of new kill element, which has the compositive functions of both KE and HE projectile, without dynamite and fuze.

In order to ascertain the pivotal factors affecting the lateral effect of PELE,a series of experiments of PELE projectiles impacting steel plate were made with different jacket materials,filling materials,impact velocities and impact angles.

With impact velocity between 400～900 m/s,after PELE perforates the target,the amount of the debris and the covering area increase and the lateral effect is intensified.

To analyze the influence of target thickness on the lateral effect of PELE(Penetrator with enhanced lateral effect),by changing target board thickness,simulations and experimentations are carried out on PELE impacting target perpendicularly in the same speed.

Research on transverse effect of three axis piezoresistive accelerometer

According to the practical design experience of the curve beam in Dongxiao South Road of Guangzhou City, the article analyzes the influence of the prestressed transverse effect of the curve beam on the main beam and substructure, and the curve beam how better to prevent the web from dilapidating on the construction.

By the set up which used to measure the transverse effect coefficient of the strain gauge, the unidirectional strain site was gotten, and attested to the exist of the fiber Bragg grating s transverse stain effect.
