TSL Engineering provides support to companies in the study, design, and verification of complex mechanical structures through the use of computational mechanics and the development of numerical models for FEM analysis.


TSL Engineering can carry out the study, development, and verification of structures subjected to dynamic loads, simulating in HyperWORKS® and LS-DYNA® environments both the behavior of structures to design loads and their response to dynamic-impulsive stresses.

In addition to computational mechanics, TSL Engineering complements other tools aimed at improving model reliability and virtualizing real objects to be subjected to FEM calculations: small-scale tests, laser scanners, and 3D printing.

TSL Engineering’s computational mechanic services address multiple sectors and apply to different types of products:

Road infrastructure

Simulations on road safety barriers, terminals, crash attenuators, motorcyclist-saving devices, lighting poles, and road sign support, bridge pier protection, parapets.

Road safety

Specifically, in this area, the use of FEM analysis allows:

  • the design of road restraints, intrusion barriers, dissipators, singular point protection solutions, programmed energy absorbing lighting poles, and integrated structures for road and highway sound insulation;
  • the verification of the operation of road safety barriers under non-standard crash conditions or installation other than crash tests.
  • The design and verification of transitions between road barriers;
  • the study of solutions for the rehabilitation of road safety barrier installations;
  • the numerical evaluation of impact severity indices such as ASI, THIV, PHD, HIC, etc.
  • The verification of the passive safety level of support structures for road equipment;
  • the verification of the behavior of tested and modified barriers according to standard UNI EN 1317-5:2012;


Detailed mechanical design, for the verification and structural optimization of individual components (interior fittings, crates, frames, bogies, shock absorbers, front ends) and entire carriages.


To enable optimization of individual components of the entire vehicle, selection of innovative materials, and analysis of passenger compartment comfort.


Evaluation of key biomechanical indices during impact, the study of passenger dynamics inside a vehicle during an impact, simulation of pedestrian-vehicle impacts, etc.
