Transformations of Stress and Strain

Transformação da tensão plana
Transformação da tensão plana
Consider a point on a cube experiencing plane stress, defined by its stress components. If the element rotates by an angle, its stress components change. ...
Principais tensões
Principais tensões
The normal and shearing stress equations of the transformed plane, when graphed, form a circle that demonstrates their relationship for any given angular ...
Tensões principais: resolução de problemas
Tensões principais: resolução de problemas
Two planes that are at right angles carry shearing stress along with tensile and compressive stresses. With known stress values, determine the principal ...
Círculo de Mohr para estresse de avião
Círculo de Mohr para estresse de avião
Mohr's circle is a visual representation of stress transformation on an element. The stress components in this element are plotted on a graph to ...
Estado geral de estresse
Estado geral de estresse
The general state of stress refers to the various forces and pressures an object experiences. Consider a tetrahedron with one face perpendicular to a line ...
Critérios de escoamento para materiais dúcteis sob tensão plana
Critérios de escoamento para materiais dúcteis sob tensão plana
Structural elements and machine parts made from ductile materials are designed to resist yielding under an expected load. The yield point is identified ...
Transformação da deformação plana
Transformação da deformação plana
Consider a long bar subjected to uniformly distributed loads on its sides. In such bars, the transformation of plane strain under a rotation of coordinate ...
Círculo de Mohr para tensão plana
Círculo de Mohr para tensão plana
Mohr's circle analyzes plane strain by plotting points with the abscissa equal to the normal strain and the ordinate equal to half the shearing ...
Análise tridimensional da deformação
Análise tridimensional da deformação
Three-dimensional strain analysis uses principal stress axes to evaluate deformation in elastic, homogeneous materials. A small cubic element, when ...
Medidas de deformação
Medidas de deformação
Strain measures the deformation or displacement in a material. Normal strain is calculated by comparing lengths before and after a load is applied. A more ...
