Line tension simulations were implemented to study the glide of a single dislocation through an array of randomly distributed point obstacles. The strength of each obstacle in the glide plane was populated from an assumed distribution, mimicking what might be expected in engineering alloys containing precipitates. The effect of changing the width of the distribution was investigated. It was found that the assumption of a uniform strength gives a lower bond to the critical resolved shear stress.
