This research reveals the efficiency of seismic isolation system in the form of rubber-metal supports with different height buildings at multi component seismic impact. As an example, seismically insulated monolithic reinforced concrete 5, 9 and 16 story buildings are considered. The solution of the problem is obtained by a direct integration of the motion equations for an explicit scheme in fi...

 Thin-walled energy absorbers are used to reduce accident induced damages. In this study, thin-walled stainless steel structures in quasi-hemisphere geometry were subjected under quasi-static loading with Santam 150KN apparatus. Experimental results were compared with results of numerical simulations by LS-DYNA and it was shown that there is a good agreement between experimental and numerical r...

Abstract An alternative approach to calibrate material models is proposed. The entire displacement field of a specimen measured with DIC system was converted into boundary conditions by the Envyo® mapping software. These were imposed on all nodes in corresponding LS-DYNA® simulation model. In this way digital twin geometry and experimental kinematics obtained. Considering local stress equilibri...

Recently in the field of sheet metal forming, servo press, which can control the speed and position of the tool using a servo motor, is attractive method. Development process of servo press method is accelerated as the capacity of servo motor become bigger. In the future, it’s expected as a great alternative plan to replace conventional press method in order to improve quality, increase product...

This is a summary of results with Dyna, a class of architectures for intelligent systems based on approximating dynamic programming methods. Dyna architectures integrate trial-and-error (reinforcement) learning and execution-time planning into a single process operating alternately on the world and on a learned forward model of the world. We describe and show results for two Dyna architectures,...

Mechanical weeding in paddy fields is a green and environmentally friendly way to control weeds, which has the advantages of reducing amount pesticides improving physical structure soil. This paper briefly describes composition relevant parameters mechanical environment rice fields. Using Creo 5.0, HyperMesh 2017, LS-PrePost LS-DYNA software jointly simulate interaction process between inverted...

Abstract Wire-explosion impact forming (WEIF) is a process based on coupled effect of gaseous, liquid, and solid media, the experimental work alone not sufficient to properly show this complex process. To understand plastic deformation behavior workpiece under action shockwave load, WEIF AA5052 tubes were simulated in LS-DYNA by considering fluid/structure interactions. Then, stress, displaceme...
