In order to satisfy the need for good quality UNDerwater EXplosion (UNDEX) response estimates of naval platforms, TNO developed two 3D simulation tools: the Simplified Interaction Tool (SIT) and the hydro/structural code 3DCAV. Both tools are an add-on to LS-DYNA. SIT is a module of user routines for generating the UNDEX loading and accounts for...

In order to satisfy the need for good quality UNDEX response estimates of naval ships, TNO developed the Simplified Interaction Tool (SIT) for underwater shock analysis. The SIT is a module of user routines linked to LS-DYNA, which generates the UNDEX loading on the wet hull of a 3D finite element model of the ship structure by means of...

Maritime Improvised Explosive Devices (MIEDs) such as small boats filled with explosives are likely to be a threat in future combat scenarios. For example the suicide attack against the USS Cole in Yemen (October 2000) has shown how disastrous MIEDs can be. With relatively simple means a complete compartment of a ship can be flooded, with...

Three-dimensional simulations were done of a heavy underwater shock trial on a floating cylinder, which was executed in 1996. The analyses were done using the so-called Simplified Interaction Tool, an approximate interaction method developed by TNO as an add-on to LS-DYNA. The analysis was continued beyond cavitation closure into the whipping...

This paper shows the use of the Optimal State Estimation Method (OSE) for estimation of slamming forces for model experiments. The OSE estimates the external loads using the response of the model and calculated natural modes. The response is measured with several accelerometers to allowthe OSE to estimate the response of the flexible modes which...

At the TNO Center for Maritime Engineering several tools are available for the analysis of naval vessels loaded by underwater shock. These tools have been developed in close cooperation with the Royal Netherlands Navy, and range from high level codes (very global models) based on standard pulse shapes, via medium level codes using a beam model...

In the joint US-NL research program DYCOSS (an acronym for Dynamic Behavior of Composite Ship Structures), a data analysis tool has been developed. The tool contains a mathematical method called the Optimal State Estimation method (OSE) and a Graphical User Interface (GUI). The OSE-method utilizes a reduced model of the ship consisting of a set...
