Effect of end-clamping constraints on bending crashworthiness of square profiles
Estrada Barbosa, Quirino (2021-07-16)The bending crashworthiness performance of thin-walled structures is affected by several factors such as the end-clamping constraints. The end-clamping configuration should be carefully investigated since it is an important ... -
Effect of radial clearance and holes as crush initiators on the crashworthiness performance of bi-tubular profiles
Estrada Barbosa, Quirino (2019-07-01)The use of bi-tubular structures has gained importance in the design of energy absorption systems for protectionof passengers in train collisions. Therefore, it is critical to improve the crashworthiness performance of ... -
Energy absorption of single and multi-cell profiles under bending load considering damage evolution
Estrada, Quirino (2018-05-14)In this paper, the energy absorption response of single and multi-cell profiles with different cross sections under bending load is presented. Emphasis was given to the modeling of damage initiation criteria and damage ... -
Energy absorption performance of concentric and multi-cell profiles involving damage evolution criteria
Estrada, Quirino (2018-03-01)Many advantages are attributed to concentric and multi-cell columns, respect to single cell structures, which made them useful for applications in automobile design. The current paper analyzes the effect of cross-section ... -
Finite element simulations of the bending resistance of square profiles with topological modifications
Estrada Barbosa, Quirino (IOP Conference Series: Materials Science and Engineering, 2019)Bending resistance is one of the most important requirements in automobile structural members when lateral crashes occur. For this purpose, the current paper studies the bending and crashworthiness capacity of square ... -
Numerical evaluation of friction effects on the energy absorption of square profiles under bending load
Estrada Barbosa, Quirino (IOP Conference Series: Materials Science and Engineering, 2019)Friction is often associated with undesirable effects on mechanical systems. However, friction could be useful to increase the energy absorption capacity of thin-walled structures subjected to bending loads. The current ... -
