Abstract:

The Riedel–Hiermaier–Thoma model, which is available in ANSYS Autodyn since 2000 as a description of concrete and similar geological materials in highly dynamic loading situations, has recently been implemented in the multi-purpose Finite Element code LS-DYNA. This article gives a brief overview of the physical details and verifies the new implementation by comparing single element test results with the established Autodyn code. Four real cases, ranging from low to very high pressure loading by impact, penetration and blast, are used to demonstrate thereafter the validity of the model in a wid

Abstract:

Purpose is to study the impact of explosive waves in an urban environment using comprehensive numerical modeling. A series of simulations were conducted using ANSYS AUTODYN software, allowing us to accurately replicate the dynamics of explosive wave interactions with urban structures. The methods used involves calculations through modeling and analysis of results. The obtained research results demonstrate that the application of numerical modeling with ANSYS AUTODYN allows for highly precise prediction of the influence of explosive waves on urban structures. These methods effectively model com

Abstract:

The formulations of the advanced concrete RHT model adopted in AUTODYN are investigated and numerical studies are conducted to study the RHT model’s actual performances under various loading conditions. It is found that using of default values in the RHT model is not able to simulate the realistic behavior of concrete under various loading conditions. Thus modified parameters in the RHT model are proposed to better capture the realistic behavior of concrete under such loading conditions. Furthermore, numerical simulation of normal concrete slabs and multilayer concrete slabs subjected to blast

Abstract:

The rolled homogeneous armour (RHA) plate is commonly used for armoured vehicle skin. Preliminary predictions of the deflections from RHA plate subjected to blast loading is important for establishing guidelines before it is used in vehicle skin. The goal of this work is a reliable technique for predicting the RHA plate response subjected to blast loading, and the empirical result performed by other researchers will be taken as a reference. Based on selected references, a small number of assumptions lead to the developed Single Degree of Freedom (SDOF) idealised models. This paper provides an

Abstract:

Pyrotechnic devices have been employed in satellite launch vehicle missions, generally for the separation of structural subsystems such as stage and satellite separation. Expanding tubes are linear explosives enclosed by an oval steel tube and have been widely used for pyrotechnic joint separation systems. A numerical model is proposed for the prediction of the proper load of an expanding tube using a nonlinear dynamic analysis code, AUTODYN 2D and 3D. To compute a proper core load, numerical models of the open-ended steel tube and mild detonating tube encasing a high explosive were developed

Abstract:

The use of CFD codes has become widespread to solve the shockwave propagation problem, as they are able to successfully model explosions. Using the structured grid spherically and cylindrical charges cannot be modelled in 3D, thus remapping techniques have been developed to map spherical shockwaves from 1D to 2D and then to 3D. This method highlights the importance of the accuracy of the 1D model, which is mainly dependent on the mesh size. This study aims at finding the required division ratio for the calculation domain.

Shaped charge (SC) is a mechanism used by defence industries as anti-armored weapon to penetrate armored plates. Numerous studies have been conducted on the shaped charged effects.

The experimental data is then verified by simulation to proof that it can be used to predict the SC penetration data. This pa

Abstract:

Smoothed Particle Hydrodynamics (SPH), a computational method as part of ANSYS Autodyn software is widely employed for simulating natural fragmentation phenomena and all others process follow with large deformations. The goal of this study is to investigate the impact of particle size on key parameters such as fragment velocity and the total number of fragments. The research focused on the 105 mm M1 artillery projectile, aims to examine the relationship between particle size and fragmentation phenomena. The Johnson-Cook failure model was applied to the projectile case and Johnson-Cook strength
