Simulations of Ductile Fracture in an Idealized Ship Grounding Scenario Using Phenomenological Damage and Cohesive Zone Models [PDF]
, 2013 Two complementary simulation methodologies for ductile fracture in large sheet metal components are presented and evaluated in this paper. The first approach is based on the phenomenological dilatational plasticity-damage model developed by Woelke and ...

Study of the size effect for non-alloy steels S235JR, S355J2+C and acid-resistant steel 1.4301 [PDF]
AIP Conference Proceedings, 2016 A change in the dimensions of a specimen vs. the reference size can affect fatigue properties of a material. This phenomenon is referred to as the “size effect”. The study concerned checked how this effect can influence non-alloy steels S235JR, S355J2+C and acid-resistant steel 1.4301. Two specimen sizes and two load types were tested.

Research on the mechanical properties of C45/S235JR multilayer steel systems
Procedia Manufacturing, 2019 Abstract The main objectives of the paper are to determine the mechanical characteristics of the multilayered steel by hot forging. The approach is to obtain bimetallic layered steel by hot forging. This new multilayer system combines the advantages of both materials and reduces the major inconvenience of each one taken separately.
