摘要： Methods, program products, and computer systems for estimating a stress of a toughened structural adhesive polymer are provided. One method comprises selecting a strain, a strain rate, a temperature, or a combination thereof at which the stress is to be estimated. A value of a strain-hardening stress of the toughened structural adhesive polymer is determined, wherein the value of the strain-hardening stress is dependent on the temperature and the strain. A value of a non-strain-hardening stress of the toughened structural adhesive polymer is determined, wherein the value of the non-strain-hardening stress is dependent on the strain, the strain rate, and the temperature. The value of the strain-hardening stress is added to the value of the non-strain-hardening stress to obtain an estimated total stress.

摘要： A method for monitoring the presence of an adhesive between two metal workpieces includes measuring the depth of indentation made by electric resistance weld electrodes by measuring the advance of the weld electrodes, and comparing the measured depth of indentation with the depth of indentation that is known to occur when the presence of the adhesive between the metal workpieces minimizes the shunting of weld current and thereby affects the depth of indentation. If the adhesive is absent, a supplemental electric resistance weld is made to compensate for the absent adhesive. The invention is applicable to both adhesive bonding, where only adhesive is used to attach the workpieces, and weldbonding, where an electric resistance weld is made atop a layer of adhesive.
摘要翻译：用于监测两个金属工件之间的粘合剂的存在的方法包括通过测量焊接电极的前进来测量由电阻焊接电极产生的压痕深度，并将测量的压痕深度与已知的压痕深度进行比较当金属工件之间的粘合剂的存在使焊接电流的分流最小化并由此影响压痕深度时，会发生这种情况。如果不存在粘合剂，则进行补充电阻焊接以补偿不存在的粘合剂。本发明可应用于粘合剂粘合，其中仅使用粘合剂来附接工件，以及焊接，其中在一层粘合剂上方形成电阻焊接。

摘要： A method is provided for attaching a fastener to the inside wall of a member. The fastener may be a bolt or a nut having a shank and a shaped head with head portions radiating from the shank. A hole is made in the member and has a shape closely corresponding to the shape of the head. The head of the fastener is inserted into the shaped hole and the fastener is reoriented so that the head engages with the inside walls of the member and therefore the fastener cannot be withdrawn. Electric current is applied to the fastener and the member to bond the head to the inside wall of the member either by heat curing an adhesive coating the head or by creating an electric resistance projection weld between the fastener head and the member.

摘要： A fastener is provided for attachment to a workpiece by a friction stir process. The fastener includes a base having an underside adapted to seat upon the workpiece and a fastener portion attached to the top side of the base. An anchor portion projects from the underside of the base and is adapted to be rotated and advanced at high speed and inserted into the workpiece by friction stirring of the workpiece.

摘要： A closure panel assembly includes an inner and an outer panel, the inner panel having a crimped edge surface feature and a textured surface feature such as a set of radial projections or asperities. Adhesive material is applied between the panels, and the outer panel is hemmed and adhesively bonded to the inner panel. The surface features affix the panels together without induction or intermediate heat curing of the adhesive material. The outer panel has a hemmed edge enclosing the crimped surface feature, with the adhesive material positioned therebetween to form a seal of a relatively low shrinkage rate. A method of forming the closure panel assembly includes forming a first and second surface feature on the inner panel, such as by using swaging and coining, respectively, applying adhesive material therebetween, and hemming the panels to form a hem seam.

摘要： A method of welding two or more workpieces employing a motion-controlled electrode that reduces temperature and residual stresses at a workpiece-to-electrode interface is disclosed. During a first period of time, a first electrode force is applied to the workpieces to be welded, and a weld current is applied that causes heating of an associated workpiece-to-workpiece faying surface, the first electrode force being applied at a first electrode stroke. A temperature of the faying surface indicative of a weld nugget formation thereat is determined, and in response thereto the electrode force is reduced to a second level during a second period of time while maintaining a constant electrode stroke. During a third period of time, the electrode force is further reduced to a third level while simultaneously reducing the electrode stroke to a second level. Welding is stopped after the third period of time, resulting in a weld joint having reduced residual stresses and reduced likelihood of stress crack formation.
