Concrete Bridge Girders with Exposed Flexural Reinforcement
… failure with no reduction in yield capacity. The Strain Compatibility Analysis derived by Harris was enhanced to involve realistic concrete stress-strain relationships and was validated experimentally using five 4-metre T-section specimens subjected to simultaneous point and uniformly distributed …

Use of Photogrammetry Aided Damage Detection for Residual Strength Estimation of Corrosion Damaged Prestressed Concrete Bridge Girders
… of a box beam and an I-beam estimated using strain compatibility analysis were validated with the actual capacities at failure sections determined from four destructive tests conducted by Al Rufaydah (2020). Along with the reduction in the cross-sectional areas of strands, limiting the …

Prostate Tissue Motion Tracking and Ultrasound Elastography Using Tissue Mechanics Derived Constraints
… and test algorithms that output stiffness, strain, and displacement data captured by ultrasound radio frequency readings, offers a potential solution to these challenges. An initial algorithm utilizing dynamic programming and analytic minimization estimates the radial and angular …

Retrofit of Reinforced Concrete Beams using Externally Bonded and Unbonded Fiber Metal Laminate
… applied loads were measured at the midspan, and strain data wasrecorded along the length of the retrofits. Four beams were retrofitted with FML, two with FRP, and one served as a control specimen that did not have a retrofit. In order to prevent a premature debonding failure between the RC beam …

Response of reinforced concrete to reverse cyclic loading
… stresses in cracked concrete. An iterative strain compatibility approach using a nonlinear bond stress-slip relationship was implemented into a computer program. The program indicated that monotonic tension stiffening does not decay with increasing strain. Analyses also demonstrated that the …

Evaluation of Hybrid-Composite Beam for Use in Tide Mill Bridge
… made within it. Such assumptions include strain compatibility and linear-elastic behavior. Three HCB's were tested at the structures laboratory at Virginia Tech. During individual beam tests, the predicted behavior of the FRP box and prestressing strand agreed with experimental results. …

Influence of sand friction angle, grout stiffness, and confinement on the behavior of acrylamide and sodium silicate grouted sand
… sand friction is appropriate when the failure strain of grout exceeds at least 4 times the failure strain of ungrouted sand, due to strain compatibility. Additionally, acrylamide-grouted sand unconfined compressive strength models developed from 25 compression tests are presented using the …

Design of materials with small magnetic hysteresis: the unexpected role of magnetostriction.
… alternative reversal paths that comply with strain compatibility conditions and this results in reduced coercivity. These alternative magnetization paths manifest as distinct magnetic domain patterns, which emerge as local energy minimizers under varying applied fields. Notably, even small …

Geometry, evolution and scaling of fault relay zones in 3D using detailed observations from outcrops and 3D seismic data
… shows that complex 3D patterns of fault-related strain commonly develop during the geometrically coherent growth of a single fault-array. However, if the component of continuous deformation was not added to the throw profile, the fault-array could have been misinterpreted as a series of isolated …

Inelastic Seismic Response Of Reinforced Concrete Buildings With Floor Diaphragm Openings
… IDARC2 is enhanced by modifying the fiber model: strain compatibility) computation routine involved in obtaining the idealized moment-curvature curves of floor slabs with openings: symmetric and nonsymmetric). Also, a new option is added so that the user can over-ride IDARC2 idealized …
