Field stresses in SIGMA/W can be used to establish the initial stress of the subsurface. This webinar demonstrates a practical example using the Field Stresses feature in SIGMA/W, as well as some practical tips for simulating initial stress in the subsurface.

Establishing the initial stress in the subsurface is key to conducting stress-strain analyses that captures the behaviour of the physical system. The presence of high in situ stress, for example, can lead to rock bursts or significant deformations in mining and tunnel applications. High stresses environments are common in complex geological systems in which tectonics or other geological processes lead to over-stressed rock, or in geotechnical applications at great depths. This webinar reviews field stresses and how they are used, including a practical example in SIGMA/W and tips for avoiding potential pitfalls.
