The stress is predicted to be infinite at the re-entrant corner. Hence, the finite element method based on linear elastic material models will never yield convergence (no matter how many […]

Usually angles are connected to gusset plates by bolting or welding only one of the two legs. This leads to eccentric tension in the member, causing non-uniform distribution of stress […]
Sand and rock show practically no creep, except at very high stress levels.
Primary consolidation is the change in volume of a fine-grained soil caused by the expulsion of water from the voids and the transfer of stress from the excess porewater pressure […]
Relaxation is a decrease in load or stress under a sustained constant deformation.
A brittle material fractures when the applied stress reaches the ultimate tensile strength of the material.
The ratio of the maximum stress to an average stress in the system is the stress concentration factor.
When component geometry changes, such as at a hole in a plate, the stress at that location is elevated.
When some bars are short, it is necessary to splice them by lapping the bars a sufficient distance to transfer stress through the bond from one bar to the other.
The critical sections for development of reinforcement in flexural members are: At points of maximum stress. At points where tension bars within the span are terminated or bent. At the […]
The factors involved in controlling main cracks are the reinforcement stress, the bond characteristics of reinforcement, the distribution of reinforcement, the diameter of the steel bars used, the steel percentage, […]
Creep increases with an increase of stress in specimens made from concrete of the same strength and with the same duration of load.
Poisson’s ratio is the ratio of the transverse to the longitudinal strains under axial stress within the elastic range.
The modulus of elasticity can be defined as the change of stress with respect to strain in the elastic range.
High local stress concentrations are not usually important in ductile materials under static loading situations, because the local yielding resulting form these concentrations causes a favorable redistribution of stress.
Brittle fracture is initiated by the existence or formation of a small crack in a region of high local stress.
For most metallic materials, elastic deformation persists only to strains of about 0,005. As the material is deformed beyond this point, Hooke’s law ceases to be valid, i.e. stress is […]
The first yield criterion for a combined state of stress for metals was that proposed by Tresca who suggested that yielding would occur when the maximum shearing stress at a […]
For some materials such as concrete in a simple compression test, there is a region beyond the failure or peak point in which the slope of the stress-strain curve is […]
For most materials after the initial yield point has been reached,the stress-strain curve continues to rise although the slope becomes progressively less, until the slope falls to zero as failure […]
When the material of a structural component is stressed beyond its elastic limit, the stress will seize to be proportional to the strain, Hooke’s law will no longer apply, and […]
The kern is the area around the center of gravity of a cross-section within which any load applied produces stress of only one sign throughout the entire cross-section.
Let the beam be subjected to bending in the plane of symmetry. If the bending moment is small, the stress and the strain vary linearly across the section. When the […]
On the plastic approach the strain and stress are proportional to one another up to the yield stress at which the strain increases indefinitely without any further increase in stress.
