Full-scale collapse testing of a steel stiffened plate structure under axial-compressive loading at a temperature of −80°C

Abstract

The aim of the paper was to develop a test database of the ultimate strength characteristics of full-scale steel stiffened plate structures under axial compressive loading at a temperature of -80 o C. This paper is a sequel to the authors' articles (Paik et al. 2020a,

Introductory Chapter: Low-Temperature Technologies

“…Mechanical properties were considered, tension and compression tests at low temperatures and cryogenic conditions, and later, a phenomenological relation of engineering stress versus engineering strain of the material was formulated, and then, the model was used into the LS-DYNA implicit code. Comparison results of the NLFEM model data with the experimental results from the full-scale test presented the similarity of the trends [18,19].…”

The influence of residual stress on the ultimate strength of longitudinally compressed stiffened panels

“…Recent advancements include the developments of novel methodologies for predicting the ultimate strength of ship hull girders [11][12] and structural components [13][14]. In addition, the understanding in the collapse mechanism of marine structures is much improved attributing to numerous investigations on the ultimate strength performance of stiffened plated ship structures in relation to slenderness [15][16][17][18][19], initial imperfection [20][21], boundary condition [22], secondary loading [23][24][25], cyclic loading [26][27][28][29][30][31], arctic environment [32][33][34][35][36], elevated temperature [37], corrosion [38][39][40][41][42][43], fatigue crack [44] and accidental damage [45][46][47][48][49].…”

An adaptable algorithm to predict the load-shortening curves of stiffened panels in compression

“…The former could occur in the transitional area with varying thicknesses and the latter could be found on the side shell panels. The ULS assessment of stiffened panels in exceptional conditions such as artic environment and elevated temperature may refer to the recent works by Paik et al (2020aPaik et al ( , 2020c and Fanourgakis and Samuelides (2021) respectively. The load-shortening behaviour of stiffened panels under cyclic axial load, which could occur in a series of storm waves, was investigated by Paik et al (2020b) and Li et al (2019).…”
