Statistical consideration of fatigue damage accumulation
Masaharu Kato,Tsutomu Mori +1 more
TL;DR: In this paper, a statistical analysis has been conducted to model the damage accumulation processes during stress-and strain-controlled fatigue tests, and it has been found that such fundamental and yet quite empirical equations to describe the well-known Coffin miner laws can be derived in a consistent manner using the statistical approach.

Integrating the Results from Process Simulation into Fatigue Life Prediction
TL;DR: In this article, the authors integrate process simulation into fatigue analysis and use it for forming simulation of steel sheet-metal as well as sand and die casting of aluminum and magnesium, which can be used as indicators for local material properties.

Residual stress prediction in large autobody panels
TL;DR: In this article, a method of estimating the deformation induced residual stresses in a sheet metal pressing is presented using plasticity theory, the principal strains obtained from grid square strain analysis are converted to flow stresses in two chosen tool-reference directions.

Effects of yield surface shape on sheet metal forming simulations
TL;DR: In this article, three phenomenological yield criteria are adopted to describe the plastic behavior of sheet metals with normal plastic anisotropy. The sheet metals are assumed to be elastic-plastic, rate-sensitive and incompressible, and a thin shell finite element formulation based on the virtual work principle is derived for the three yield criteria.
