plastic strain

A hybrid grid method was used to determine the principal plastic strain distribution in a deformed area of a sheet metal piece.

It was originally applied to elastic-plastic problems, ones in which the plastic strain is of the order of the elastic one.

The final configuration is identical to that in (a), and the total plastic strain is six atomic spacings.

The powerful stress is big enough to cause plastic strain and plastic flow on the interface which can provide good conditions for bonding.

In sheet metal forming processes under tensile stresses, the plastic strain limit can be evaluated. Much experimental work can be saved.

Thirdly, plastic strain ratio and strain hardening index are the two key parameters of material's formability.

The dynamic strain aging of low carbon steel is the main reason of low plastic strain ratios value of the ferrite rolled strip.

The test results can be useful for study of model's large deformation and plastic strain in view of incomplete geometric similarity. 3.

The elastic parameters of anisotropic rocks are the functions of plastic strain and loading angle.

Through analysing and discussing in calculating plastic strain distribution map and safety factor received.

The strain-fatigue-life of materials is related to the plastic strain at the crack-tip.

The maximum plastic strain of the alloy increased with the increase of temperature.

The existence of rigid etch stop layer helped to reduce the thermal stress and plastic strain.

Low-fatigue properties of 3 hoop was tested. Results show that the density of cyclic plastic strain energy is relative to hoop damage.

It is observed that the degradation index is reduced with increase of accumulative plastic strain.

Meantime, with the decrease of cooling rate, the plastic strain increases.

Based on the test results, an empirical accumulative plastic strain model is proposed by introducing a comprehensive impact parameter.

At the meantime, cumulative plastic strain will develop.

Iron and steel - Methode of determination of the plastic strain ration r of steel sheet and plate.

and bring the larger plastic strain in interface of matrix and fiber.

Simultaneously, an ideal plastic element was introduced to simulate the development of cumulative plastic strain during cyclic loading.

The reason for axial snap-back is that the recovery of axial elastic strain is faster than the increase of axial plastic strain.

Slip and twinning are the most important modes of deformation and account largely for the plastic strain that is generated before fracture.

At 15% FIMA burnup level, the stress and plastic strain level in the matrix is very high.
