Transformations of Stress and Strain

Transformation der ebenen Spannung
Transformation der ebenen Spannung
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. ...
Hauptspannungen
Hauptspannungen
The normal and shearing stress equations of the transformed plane, when graphed, form a circle that demonstrates their relationship for any given angular ...
Hauptbelastungen: Problemlösung
Hauptbelastungen: Problemlösung
Two planes that are at right angles carry shearing stress along with tensile and compressive stresses. With known stress values, determine the principal ...
Mohrs Kreis für ebene Spannung
Mohrs Kreis für ebene Spannung
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 ...
Allgemeiner Spannungszustand
Allgemeiner Spannungszustand
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 ...
Fließkriterien für duktile Materialien unter ebener Spannung
Fließkriterien für duktile Materialien unter ebener Spannung
Structural elements and machine parts made from ductile materials are designed to resist yielding under an expected load. The yield point is identified ...
Transformation der ebenen Dehnung
Transformation der ebenen Dehnung
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 ...
Mohrs Kreis für ebene Dehnung
Mohrs Kreis für ebene Dehnung
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 ...
Dreidimensionale Dehnungsanalyse
Dreidimensionale Dehnungsanalyse
Three-dimensional strain analysis uses principal stress axes to evaluate deformation in elastic, homogeneous materials. A small cubic element, when ...
Dehnungsmessungen
Dehnungsmessungen
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 ...
