A fast and accurate model for the creation of explosion fragments with improved fragment shape and dimensions

David Felix et al.

Summary: By improving the explosion model based on Finite Element Analysis (FEA) with Mott's equation, a fast simulation model is developed that can be used for quick predictions and real-time simulations to determine the number, weight, size, shape, and origin of fragments created by an explosion.

Defects in additive manufactured metals and their effect on fatigue performance: A state-of-the-art review

Niloofar Sanaei et al.

Summary: Additive manufacturing is emerging as an alternative method for producing unique and complex parts, with fatigue performance being a key consideration. Defects such as Lack of Fusion, porosities, and un-melted particles can affect fatigue performance, but can be minimized through process optimization and post-processing. Analytical techniques can reduce the need for costly fullscale testing for assessing reliability in fatigue performance.
