The mechanical behavior of T-stubs bolted connection with two and four bolts per row under monotonic cyclic loading is analyzed in this paper using a 3D finite element model. aim the model that takes into account material geometrical nonlinearities to obtain evolution prying forces throughout cycles loading. numerical also used compare those row. results are prepared be as basis for proposing a...

Accurate sheet metal simulation often requires advanced strain-path dependent material models, in order to predict the response under complex loading conditions, including monotonic, reverse and orthogonal paths. More more flexible models imply higher costs terms of parameter identification, computer implementation time, robust comparison is compromised by inconsistent predictions monotonic loa...

A comprehensive experimental study on the structural behaviour of stainless steel T-stubs in Grade EN 1.4003 ferritic and employing A4–80 bolts is reported this paper. total 17 various geometric configurations including both single double bolt rows were tested under monotonic tension. The focus tests was failing predominantly mode 1. Auxiliary tensile performed coupons extracted from T-stub fla...

A fully modularized framework was established to combine isotropic, kinematic, and cross hardening behaviors under non-monotonic loading conditions. Three sets of state variables were defined and applied to consider the effects of, a) loading history, b) twinning and de-twinning and c) different pre-strain. Experiments under two types of nonproportional loading conditions were conducted along d...

Refractory masonry (refractories) is exposed to in-service loads of different types. To rationalise the design and failure analysis, differences under cyclic monotonic loading were studied. For samples silica refractories tested in wedge splitting set-up global parameters crack trajectories assessed. Under loading, higher fracture energy lower brittleness at seen. Cracks modes had similar non-l...

Advanced hardening models accurately describe the transient plastic behavior (reyielding, stagnation, resumption...) after various strain-path changes (reverse, orthogonal...). However, a common drawback of these is that they usually predict monotonic loading with lower accuracy than regular isotropic models. Consequently, finite element predictions using may sometimes lose in accuracy, spite t...
