Rock Masses
Modeling of Underground Openings/Probability of Slope Failure/Fracture of Intact Rock
While soil mechanics has been the dominant interest of Civil Engineers since Karl Terzaghi's recognition of the principle of effective stress, rock mechanics is becoming increasingly...

Integral Equation Methods in Fracture Mechanics

Hybrid Model for Discrete Cracks in Concrete

Stress Analysis of Buried Pipelines

Possible `Ductility' in a Material with Planar Discontinuities

Finite Element Analysis of Discontinuous Channel Flow

Finite Element Method for Interface Problems
A method for incorporating interface discontinuities in a finite element analysis of discontinuous media is presented. For computational purposes the procedure is implemented into the...

Experimental Evaluation of Composite Action
Experimental results for a layered lumber diaphragm are presented and compared with theoretical analysis. The influences of joists, boundary members, and layer discontinuities on deflections...

Displacement Discontinuity Analysis of Mining Induced Stresses

Strain and Displacement Discontinuities in Soil
A classification is made of the various possible types of kinematic discontinuity. The commonly accepted condition that a velocity discontinuity should coincide with a direction of zero...

Torsional Analysis of Cutout Beams
The torsional deflection analysis of uniform hollow beams having a uniform cutout and subjected to a quasi-statically moving point torque is presented. An inherent deflection discontinuity...

Strength of Connection with Buried Discontinuity
A research program was conducted to investigate the behavior of buried, midplane laminar discontinuities (laminations) subjected to through thickness tension loads. The study showed that...

Failure of Riveted and Forge-Welded Penstock
This paper describes the failure and repair of a 1920's vintage 78-in. (198-cm) diam, 1-1/4-in. (3.18-cm) thick riveted and forge-welded penstock. The failure occurred at...

A Computer Program for Slabs with Discontinuities

Geomechanical Model for Rock Foundation Settlement
A geomechanical model is proposed for estimating the settlement of foundations on rock masses. Included is a rock mass model for reducing rock material properties to rock mass properties...

Comprehensive Model for Rock Discontinuities
The full understanding and analytical modeling of rock discontinuity behavior requires a comprehensive model that can describe the entire history leading to the present state of the discontinuity...

Fatigue Cracking—Problem for Welded Steel Bridges
A recent problem with welded steel bridges is fatigue cracking at welded details. Fatigue cracks begin in small flaws or discontinuities at welded connections and grow to a critical size...

Recorded Signatures of Actual Exposed Discontinuities

Rapid Calculation of Stress Intensity Factors
A method for computing stress intensity factors for cracks embedded in structural details is described. It consists of adding to accepted solutions for cracks in finite plates and bodies...

Numerical Analysis of Beams on Elastic Foundations
This note deals with a difference method, referred to as the midpoint difference method, for approximating the solutions of a linear differential equation, in the presence of discontinuities....
