一旦预见到计算机的可能性，工程界就把注意力转向解决复杂的弹性和结构分析问题，而不是依赖于材料近似强度的方法。它还使工程界能够减少对安全方法因素的依赖，并在相当大的程度上消除或减少未知因素，从而提供更准确的设计。有限元方法允许更准确的预测减少了昂贵的实验和引入模拟，从而在测试原型之前实现更便宜但更准确的设计。
Once the possibility of computers was foreseen, the engineering community turned its attention to solving complex elasticity and structural analysis problems rather than depending on an approximate strength of materials approach. It also allowed the engineering community to depend less on factors of a safety approach and to remove or reduce to a considerable extent the unknown factors and thus render more accurate designs. Finite element methods allowing more accurate predictions reduced costly experimentation and introduced simulation, thus achieving cheaper but more accurate designs before testing prototypes.
