The purpose of this study is to compare the qualitative patterns of stiffness of benign and malignant lesions matched for quantitative stiffness.
Previous studies assessing qualitative patterns of stiffness in breast lesions have not matched benign and malignant lesions for quantitative stiffness.
Patterns of stiffness in specific joints at specific times of day can be clues to certain rheumatologic conditions, Dr. Lachs said, and should be brought to the attention of a doctor.
Figure 17 also shows that the tubes with different axial compression ratio share the same pattern of stiffness degradation.
Three methods are explored (1) varying ply orientation and laminate stacking sequence; (2) introducing patterned material stiffness distributions; and (3) providing internal lateral constraints.
Here, we evaluated the effects of LVRS on left ventricular (LV) end-diastolic filling pattern, dimensions, stiffness, and performance, as well as pulmonary and systemic hemodynamics.
The experimentally validated model predictions show that a non-linear finite element analysis can predict the member behaviour, in terms of failure mode and ultimate load, yield line pattern, overall stiffness and local strain in the cold-formed profiles.
This is the optimal and the ideal behaviour in a structure but, in the other systems the pattern of stiffness sorting that, it is from high to low stiffness, have not been respected and this is the reason of increasing the cost of construction, especially for structural skeleton.
The fracture pattern, wedge stiffness, and opening micromotion are used as the comparison indices of the testing results.
An iterative approach is also developed to determine the design strength (and stiffness) pattern needed to achieve a prescribed ductility (or drift) distribution according to different dynamic characteristics of the structure and earthquake.
